pupil examination in icu

In the ICU, it is easy to divert … If the patient can cooperate with a neurological exam, assess for facial drooping, arm drift, and slurred speech. Some patients need an advanced airway for airway protection. Examination of retina (fundus examination) is an important part of the general eye examination. Pupil Size and Equality Pupil size is reported as the width or diameter of each pupil in millimeters. If the patient is receiving any sedative or analgesic, discontinue the offending agent and consider a pharmacologic reversal agent if indicated (flumazenil or naloxone). pupil examination with all patients, even with those who had periorbital edema. ), https://accessanesthesiology.mhmedical.com/content.aspx?bookid=1944§ionid=143515966.  GL, Puntillo Otherwise it is hidden from view. Symmetric, ... (ICU) arerequirement for cardiac or ventilatory support and a precariously unstableneurologic state. Has the patient had recent abdominal surgery? Hi all, :)I am a new grad working in an ICU, and I just had a general neuro question. For unstable patients, especially those experiencing signs of obstructive shock, provide adequate oxygenation, ventilation, and cardiovascular support. Recent anticoagulation and possible skin ecchymosis? Ophthalmic consultation was required if patients’ ICU stay exceeded 7 days or if the ICU staff suspected any eye problems. Mount Sinai / Presentation Slide / December 5, 2012 28 Dolls Eyes Vestibulo-Ocular Reflex. Quickly assess the patient's pulses, extremities, and respiratory status. If the patient is obtunded or unable to protect their airway, then consider intubation and initiation of mechanical ventilation.  et al. Has the patient had any recent intervention that may have caused a pneumothorax? The main focus should always be on the patient rather than solely the ventilator.  GL.  J, Fraser Then look at the monitor to assess the ECG rate and rhythm, the arterial blood pressure waveform or the NBP reading, and the pulse oximetry reading.  et al. It would be embarrassing to miss meningism in the examination of the febrile patient. Visual examination—The first thing you do as you walk into the room is observe the patient and glance at the monitor to assess whether the vital signs are stable. © 2019 Australian College of Critical Care Nurses Ltd. (2016) found a moderate level of agreement in pupil size measured by a neurosurgeon and neurocritical RN. Please consult the latest official manual style if you have any questions regarding the format accuracy. “By the time that one needs to intubate, you are dealing with a very serious problem,” he said. Terms of Use The diagnosis of brain death first requires that two board certified doctors from specific specialties examine the patient and confirm that likely he or she is brain de. NTI 2019 Expo Ed – Precision Pupillary Assessment: Using NPi ® and the Pupillometer in Critical Care. Assess for accuracy of the blood pressure reading by checking cuff or arterial catheter placement. Acute situations in the ICU are inevitable. Look into each of the patient’s eyes, examining the size of the pupils (Fig 3). Is the patient awake or unresponsive? Routine examination of the respiratory includes examining the airway and auscultating the lungs. Is the patient exhibiting signs of anxiety and agitation? Runcie • Pupils examination (size, equality and reaction to light). Does the patient have any intraabdominal surgical drains in place and is there any fluid output? However, if the patient is unstable and symptomatic with a change in mental status, hypotension, and complaints of chest pain, then treatment should focus on optimizing the patient's hemodynamic status by initiation of the Advanced Cardiovascular Life Support (ACLS) protocol for bradyarrhythmia and treat the underlying cause. The patient's clinical status and arterial blood gas findings will help guide the management decisions. At the same time observe the patient and note the level of alertness and distress. If the patient is stable continue to monitor and observe closely. Is the patient awake or unresponsive? In the ICU, it is easy to divert attention from the patient and focus on the alarming monitors and machines. Compare the shapes of the pupils. We conducted a single-centre prospective observational study in a specialised tertiary neurosciences intensive care unit. Example:jdoe@example.com. If a pneumothorax is present, determine if the patient is stable or unstable. Olson et al. Note the type of fluid therapy the patient is receiving and whether the amount or rate is accurate or appropriate based on the patient's clinical status, weight, cardiac status, and sensible and insensible fluid losses. If the patient is stable then proceed with further testing if necessary, discontinue, and/or adjust medications depending on the diagnosis and clinical scenario and treat the underlying cause. Has the urine output abruptly decreased or was there a change in color? If there is no contradiction, gently rub the patient's sternum with a closed fist to stimulate the patient. Also, the pupils may be pinpoint, small, large, or dilated. If the patient is unstable and experiencing signs of obstructive shock, immediate intervention for decompression is warranted. Ethics in ICU R.Y 1515 Interactive Presentations L.W Interactive X-rays L.W Clinical cases M.C. In an adult ICU, light levels of sedation are recommended and daily interruptions can reduce the amount of time on a ventilator and the ICU stay.3. During the accommodation reflex, the pupil constricts to increase the depth of focus of the eye by blocking the light scattered by the periphery of the cornea.

Examples include the eydrops atropine, cyclopentolate and tropicamide. Be sure to ask about the patient's last bowel movement or recent vomiting. At the same time, look at the patient and note their level of alertness and distress.  CJ, Dougall The ciliary muscles are responsible for the lens accommodation response. Purplish periorbital edema was observed at ICU admission and prevailed in 24 and This will help provide a list of differential diagnoses for the patient's respiratory status. If the patient can participate in the exam: Follow OPQRST algorithm: Onset of the event, provocation or palliation, quality of pain, region and radiation, severity, and time. F. 1630 Interactive Path Forms L.W Interactive Biochemistry, haematology coagulation L.W. If the patient is on mechanical ventilation and experiencing respiratory distress and desaturation from inadequate ventilation, are the peak inspiratory pressures elevated? Additional opioid boluses had no effect on pupil size. Although pupil reaction is not included as part of the GCS, it is often incorporated into the neurological assessment charts used in healthcare facilities in addition to the use of the GCS. Before performing a physical exam, review the patient's chart; obtain a history and gather information from the patient, relatives, medical staff, or review of notes. However, the importance of the physical examination should not be underestimated. Twenty-two participants were enrolled. Is there any known previous pertinent medical history that could be attributing to this distress? Amid these obstacles, this exam should be performed quickly and efficiently. In the Intensive Care Unit (ICU), practitioners generally prefer to record the size and equality of pupils pre- and post-light stimulation (Friedman et al., 2009, Salandy et al., 2019, Ong et al., 2019). Perform a bedside echocardiogram to evaluate right and left ventricular function and volume status to direct treatment. Determine if the patient needs suctioning of their ETT from possible obstruction or mucous plug. Observe the type of seizure activity: partial seizure, tonic clonic seizure, grand mal seizure, or status epilepticus. There was no statistically significant disagreement in assessing pupil reaction (McNemar's test p = 0.106). Visual examination—The first thing you do as you walk into the room is observe the patient, the oxygen-ventilator-patient interface (are they connected to oxygen or the ventilator?) If EKG is noted for ST-elevation myocardial infarction, obtain an immediate cardiology consultation for possible need of emergent percutaneous catheter intervention. Measurement of static pupillary size in the ICU is of importance in cases of acutely expanding intracranial mass lesions. A total of 935 paired pupil observations were obtained for both pupil reaction and size. Percentage agreement was 96.68% for pupil reaction, with Kappa coefficient, 0.841 (95% confidence interval: 0.7864–0.8956). Has the patient any recent surgery or trauma to the affected extremity? Does the monitor accurately reflect the patient's pulse and clinical condition? Has the patient received any medications that can cause hypotension? For intubated and mechanically ventilated patients, examine the endotracheal tube (ETT) position both on exam (eg, 21 cm at the lips) and on chest x-ray (CXR) (eg, ETT tip 5 cm above the carina) and review the ventilator settings and the output information. Pupil evaluation includes assessment of pupil size, shape, and equality before and after exposure to light. Check the current settings: ventilator mode, tidal volume, respiratory rate, FiO2, PEEP, and inspiratory to expiratory ratio. All pupil observations were carried out by nursing staff of the neurosciences ICU. There are various scales to assess level of sedation and pain and choosing 2 reliable scales, for example the Sedation-Agitation Scale (SAS)1 (Table 10–1) to assess the level of sedation and the Wong-Baker FACES Pain Rating Scale2 to communicate how much pain the patient is experiencing. Review current medications and possible side effects that may have precipitated the seizure. Adapted from Plum and Posner's Diagnosis of Stupor and Coma. Is the patient in NAD or in distress? Physical examination on daily rounds is a vital part of ICU management. A standardized pupil gauge should Accurate documentation of physical exam findings will identify trends or any change in a patient's clinical status. Glance at the monitor to assess the ECG rate and rhythm, the arterial blood pressure, and waveform or NBP reading and the pulse oximetry reading. Quickly glance at the patient's skin and lips for signs of cyanosis. attention among general intensive care unit (ICU) patients, but less so among neurocritical care patients. An assessment of the cardiovascular system should be obtained which includes auscultation of heart sounds, evaluation of pulses, capillary refill, and edema. ... ‘‘fixed pupil’’ OR ‘‘dilated pupil’’ OR ... as pupil examination can be dynamic and non-reactivity is occasionally reversible [32, 33]. Is the patient in no acute distress (NAD) or in distress? If the patient has a tracheostomy, assess for adequate placement in airway, adequate cuff volume, and inner cannula for patency. Normally, pupils are equal in size and about 2 to 6 mm in diameter, but they may be as large as 9 mm. Separate multiple email address with semi-colons (up to 5). A decline in mental status is the most common reason that patients with stroke are admitted into the ICU, along with the need for intubation, largely for airway protection, according to Dr. Gress.  et al. A bedside transthoracic echocardiogram is relatively quick and useful in the evaluation of the right and left ventricular function and can guide the use of intravenous fluids, vasopressors, or other cardiac agents. Acute management—If the patient is awake and in NAD, spontaneously breathing, not hypotensive and no complaints, obtain a 12 lead ECG and analyze rhythm, perform further testing if necessary, assess for drug-induced causes, and discontinue the offending medication depending on the diagnosis and clinical scenario. The cornea is hazy on slit-lamp examination, with a very high intraocular pressure. Auscultate bilateral breath sounds, assess for bilateral chest rise and perform an ultrasound of the chest to evaluate lung sliding or B-lines. Over-sedation is undesirable for a number of reasons and performing daily sedation breaks reduces length of stay on ICU. Physical examination—At the same time, look at the patient and note the level of alertness and distress. There are multiple strategies to treating a patient in respiratory distress whether it is close observation, medication, supplemental oxygenation, the need for an advanced airway, or an emergent intervention (chest tube thoracostomy). Assess the plantar response and withdrawal to pain stimuli. Relaxation and contraction of the muscles of the iris causes it to dilate (in darkness) or constrict (in bright light). Pupil examination … If your institution subscribes to this resource, and you don't have a MyAccess Profile, please contact your library's reference desk for information on how to gain access to this resource from off-campus. These include noisy alarms (eg, monitor, ventilator, IV pumps, etc), limited assessment due to sedation or analgesia, inability to easily change the patient's position, wounds, dressings and multiple invasive lines or tubes. Clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the intensive care unit. The patient's current illness and status will prioritize the exam. This heterogeneity has implications for medical education, patient outcomes, and the overuse/misuse of diagnostic testing. Make note of the measured tidal volumes, minute volumes, and peak and plateau pressures. The recipient(s) will receive an email message that includes a link to the selected article. For concerns of ischemia or compartment syndrome call the appropriate consult. This assessment should take less than 10 seconds. In the ICU, most patients are unable to self-report pain or communicate, which makes this exam more challenging. The key to a good physical exam in the intensive care unit (ICU) setting is the ability to interface this medical technology with the patient's clinical presentation.   •  Accessibility, Error: Please enter a valid sender email address. Continuous observation of vital parameters such as heart rate, blood pressure, respiratory rate, and oxygen saturation allows the medical staff to stay apprised of any acute changes and the general condition of the patient. Patients admitted to the ICU with intracranial pathology should have a more focused and detailed neurological assessment adjusted to their diagnosis and presentation. NORMAL PUPIL The pupil is an opening located in the center of the IRIS that allows light to enter the retina. This assessment should take less than 10 seconds. Perform a thorough assessment of the affected extremity's proximal and distal pulses, coolness and capillary refill. Physical examination—Is the patient in distress and experiencing severe pain, weakness, numbness, or paresthesias of the extremity? Finally the commonest cause of a dilated pupil is exposure to dilating drugs. Is the patient awake or unresponsive?  K, Is the patient in acute respiratory distress? Performing a physical exam in the ICU is often difficult. CLOSED CAPTION. Other parameters to include during respiratory examination are correlating the patient's current condition with their chest x-ray, lung sonogram (if available), and any chest tubes or drains. This chapter will demonstrate how to perform a physical examination on routine assessment and in certain critical situations in the acute care setting. If the patient is stable, consider ultrasound, computed tomography (CT) scan and/or ventilation perfusion scan of the chest. Vasculitis is a cause of fever, and its many manifestations may have been lost among the spectrum of ICU-related skin problems. Does the patient's ETT or tracheostomy need to be suctioned? Pupil to limbus ratio: Introducing a simple objective measure using two-box method for measuring early anisocoria and progress of pupillary change in the ICU J Neurosci Rural Pract. A small pool of neurosciences ICU nurses received training on the use of the NeurOptics® NPi® Pupillometer and performed all pupillometer observations. Is the patient on a ventilator or breathing spontaneously? Wong-Baker FACES® Pain Rating Scale. The ventilator alarms that are being triggered will give insight to why the patient may be in respiratory distress. Acute management—Provide a safe environment and administer a first line agent, such as an intravenous benzodiazepine (lorazepam, midazolam, or diazepam). Question 12 from the first paper of 2003 asked whether or not there is any merit to the routine practice of examining ICU patients. According to the 2013 clinical practice guidelines for Pain, Agitation, and Delirium (PAD), delirium should be assessed daily in mechanically ventilated patients.4 Delirium can occur in nearly 60% to 80% of mechanically ventilated patients and is associated with increased mortality in the ICU and long-term cognitive impairment.4 Adult ICU patients can be assessed for delirium by using The Confusion Assessment Method for the ICU (CAM-ICU)5 (Figure 10–1). https://doi.org/10.1016/j.aucc.2019.04.005.   •  Notice Glance at the monitor to assess the ECG rate and rhythm, arterial blood pressure, and waveform or the noninvasive blood pressure (NBP) reading (may need to be cycled), the pulse oximetry reading/waveform, and respiratory rate. The assessment of pupil size and reaction to light is a fundamental part of the neurological assessment; however, manual examination is prone to inaccuracies. Physical examination—Apply supplemental oxygen as needed. Pupil 1. Spine . Electronic Medical Record Integration for the NPi-200 ® Pupillometer System. Is there concern for hepatic encephalopathy or metabolic encephalopathy? Physical examination—At the same time, look at the patient for abnormal movements or shaking and note the level of consciousness and/or distress. Any changes in the patient’s …  EW, Margolin Sympathetic nervous system Dissection . Also, is the patient receiving the set tidal volume? and glance at the monitor to assess the ECG rate and rhythm, the arterial blood pressure and waveform or the NBP reading, and the pulse oximetry reading. N.E R.Y 1745 Travel To RAH Travel to RAH FMC = Flinders Medical Centre QEH = Queen Elizabeth Hospital PUPIL IN HEALTH AND DISEASE CHAIRPERSON : PROF.DR.M.S.KRISHNAMURTHY PRESENTER : DR. AMAR PATIL 2. Bowel function should also be noted and the output recorded. PUPILS .  W-BF. The use of an automated infrared pupillometer is one strategy to limit error in pupil examination. If the etiology is primary abdominal compartment syndrome, immediate surgical intervention is required for abdominal decompression. Efficacy and safety of a paired sedation and ventilator weaning protocol for mechanically ventilated patients in intensive care (Awakening and Breathing Controlled trial): a randomised controlled trial. Quickly look at the ventilator, its waveforms (tidal volume, pressure, and flow) and make note of which ventilator alarms are being triggered. If the patient is rapidly deteriorating or abruptly unstable, disconnect the patient from the ventilator and hand ventilate with a bag valve mask providing 100% oxygen and use a PEEP valve if the patient was receiving PEEP. https://accessanesthesiology.mhmedical.com/content.aspx?bookid=1944§ionid=143515966. ICU Coma Examination Cranial Nerves Pupils EOMs Corneals Gag Helps you identify a focal process producing coma in the brainstem! Make note of any drains or stomas and trend the output volumes and color. Product Implementation of Automated Pupillometers in the Pediatric ICU: Creator: Mandy Robison, University of Utah BSN Student: Description: The project objective is to create a more efficacious procedure surrounding pupillary examination by using Automated Pupillometers for pupil examination. The necessity for an indwelling urinary catheter should be addressed daily. Physical examination—At the same time, look at the patient and note their level of consciousness and/or distress. Is the patient in NAD or in distress? Healthcare providers in ICU settings often conduct subjective pupil evaluations with a penlight and the initial size of pupils is the primary benchmark for determining both pupil size and anisocoria. Ely Physical examination—Connect the oxygen or ventilator if disconnected. Consider using a doppler if the pulse is unable to be palpated. The exam and those diagnoses are covered here. Is the patient awake or unresponsive? Patients and methods: One hundred and fifteen consecutive patients presenting with coma were enrolled in this prospective cohort during the 12 month study period in the emergency room of a community teaching hospital. Clinicians have been assessing the pupils of patients with suspected or known brain injury or impaired consciousness for centuries. The main focus should remain on the patient's clinical presentation while integrating information from the monitors and diagnostic tests. Catheter . CLAUDE BERNARD HORNER . Other unstable etiologies of acute chest pain that need to be considered include thoracic aneurysm, pulmonary embolus, pneumothorax, and mediastinitis. If the patient is orally intubated with an ETT, note the position of tube at lips or teeth. However, despite the theoretical and practical training that nurses receive during their studies, this practice by nurses is not outstandingly evident in the ICU of the Internal Medicine Department. However, vital signs are not used solely to assess for pain. High-pressure alarms may indicate the following: mucus plug, pneumothorax, mainstream intubation, obstructed ETT (patient biting or mucus plug), asynchrony, or abdominal compartment syndrome affecting ability of adequate ventilation. Visual examination—The first thing you do as you walk into the room is observe the patient, are they connected to supplemental oxygen, if so what type? Check the Foley catheter for kinks and hand irrigate to assess patency. Pupils… Is the patient awake or unresponsive, in NAD or in distress? Bedside Teaching is a Powerful Learning Tool in the ICU; Foundation Copyright © McGraw HillAll rights reserved.Your IP address is Low-pressure alarms may indicate the following: air leak, extubation, tube, or ventilator disconnection; note that there are many areas on the ventilator circuit tubing that can allow for a disconnection and the tubing must be examined carefully fully along its path. On ICU day 54, the pupils were noted to be 6 mm and nonreactive. Physical examination—At the same time, look at the patient and note the overall appearance, level of consciousness, skin color (cyanosis), work of breathing, accessory muscle use, airway resistance, and airflow, and if there is ventilator synchrony versus dyssynchrony. Copyright © 2020 Elsevier B.V. or its licensors or contributors. If the patient cannot participate in this exam then look for signs of pain such as facial cues, restlessness/positioning, and/or physiological changes (rise in heart rate and blood pressure). Visual examination—The first thing you do as you walk into the room is observe the patient and glance at the monitor to assess the ECG rate and rhythm, the arterial blood pressure and waveform or NBP reading, and the pulse oximetry reading. Acute management—If the patient is unresponsive, unstable, or experiencing signs of a stroke, initiate the ACLS protocol. comatose patient, pupils are assessed per the position they are found in. The size of the pupil determines the amount of light that enters the eye. If the underlying cause is hypoxia and the pulse oximeter shows desaturation, patient-ventilator dyssynchrony and/or the ventilator is alarming, refer to the section on Acute Respiratory Distress. The pupil examination is an integral part of the neurological examination of brain-injured patients in a neurological ICU. The NPi®-200 pupillometer (Neuroptics, Laguna Hills, CA, USA) is a non-invasive device that uses an infrared camera that integrates a calibrated light stimulation of fixed intensity (1000 lux) and duration (3.2 s), allowing for a rapid and precise measure (0.05 mm limit) of the pupil size and of a series of dynamic pupillary variables (including the percentage pupillary constriction, latency, constriction …
