Extubation in Pediatric Patients: An Observational Study

Completed

Conditions studied: Anesthesia, Pediatric

In brief

The timing of extubation following surgery and anesthesia in young children is a complex decision frequently guided by the experience of the clinician. The clinician frequently must make a decision based on assimilating multiple cues that may or may not demonstrate that the patient is ready for extubation such as eye opening, conjugate gaze, spontaneous ventilation, and end tidal agent concentration. At this time there is no published data on the predictive ability of individual extubation criteria for young patients undergoing anesthesia for surgery so most practice is based solely on experience and anecdotal teaching. In some cases if the timing is misjudged and the patient is extubated too early negative airway reflexes such as breath holding and laryngospasm may take over creating a critical situation in which the patient forgoes gas exchange and rapidly desaturates with the potential for bradycardia and further cardiovascular collapse. Routine criteria used to determine fitness for extubation have been primarily described in the intensive care unit literature and may be less relevant in the operating room in the setting of routine general anesthetics. Most predictors including adequate tidal volume, presence of conjugate gaze, eye opening, patient movement purposeful or otherwise, low end tidal anesthetic agent concentration, response to physical or verbal stimulation and the laryngeal stimulation test have not previously been evaluated to determine their individual predictive value in deciding if the presently anesthetized patient now emerging is ready to be extubated. In order to perform a laryngeal stimulation test the patient must be breathing spontaneously and practitioner will gently move the endotracheal tube up and down stimulating the larynx. In patients in stage 2 of anesthesia, the clinician will typically observe a cough or series of coughs followed by a respiratory pause of greater than 5 seconds. In this situation the patient has not adequately passed through stage 2 and remains at increased risk for apnea, breath holding, or laryngospasm. If the patient is in stage 1 of anesthesia the clinician will observe a cough followed by a brief pause (less than 5 seconds) or almost immediate return to spontaneous ventilation. In conclusion, their exist no quantitative data on the predictive value of these various criteria for extubation and the goal of our study is determine the indivdual predictive value of different criteria in determing fitness for extubaion in young pediatric patients by recording the presence or absence of various criteria in pediatric patients at the time of extubation during routine anesthetic care.
