Effectiveness of Propofol in Mitigation of Emergence Agitation Among Pediatric Patients Undergoing Elective Surgery Under General Anesthesia: a Prospective Cohort Study

IntroductionEmergence agitation is the abnormal mental status that develops as the result of anesthesia administration during the transition from unconsciousness to complete wakefulness. It occurs in all age groups but is more common in pediatrics. If emergence agitation is not prevented, it can lead to serious life-threatening phenomena. Thus, preventing the occurrence of emergence agitation would reduce the unwanted side effects and makes emergence smooth. ObjectiveThis study aimed to assess the effectiveness of propofol in the mitigation of emergence agitation among pediatric patients undergone elective surgery under general anesthesia at Jimma University Medical Center. MethodsA prospective observational cohort study was conducted from October 1/2022 to December 30/2022 among pediatric patients aged 2-14 years who underwent elective surgery under general anesthesia. A total of 76 patients were enrolled in the study in two groups (propofol and non-propofol) with 38 patients in each. Data were collected from all study populations who fulfilled the inclusion criteria. The incidence and severity of EA were assessed by the pediatric anesthesia emergence delirium scale in the post-anesthesia care unit at different time intervals. The presence of emergence agitation was considered when the pediatric anesthesia emergence delirium scale was [≥] 12 and severity was classified as no agitation [0-11], agitation [12-15], severe agitation [[≥] 16]. The data were checked manually for completeness then entered and cleaned using Epi Info, version 7, and exported to Statistical Package for Social Sciences (SPSS) software, version 26.0 for analysis. Normality was tested using the shapiro-wilk test, and histogram. A comparison of numerical variables between the study groups was done using an independent sample t-test. Chi-square/Fischer exact test was used to compare categorical variables and presented as numbers and percentages. The incidence of EA was also presented in confidence interval and relative risk. A p-value less than 0.05 was taken as statically significant. ResultThe overall incidence of EA in both groups was 48.7% (37%-60.4%). The incidence of EA in the propofol group and non-group was 34.2% (19.6%-51.4%) vs 63.2% (46%-78.2%) respectively p=0.012, which means that EA was significantly decreased in the propofol group in comparison to the non-propofol group. There was a significant reduction in the severity of EA at time intervals of 5th and 15th minutes; P =0.012 vs 0.029 respectively. However, there was no significant difference in the severity of EA at the 30th minute between the groups; P=0.08. The relative risk of EA in the propofol group was 0.54; 95% confidence interval (CI) 0.3270.896. This showed propofol group had less risk of emergence agitation in comparison to the non-propofol group. Conclusion and Recommendation: The administration prophylactic propofol at the end of surgery is vital in reducing both the incidence and severity of emergence agitation and makes recovery smooth. Thus, we recommend the routine prophylactic propofol at the end of surgery to reduce the incidence and severity of postoperative emergence agitation in pediatric patients.
