The Effect of Intraoperative Body Temperature on Postoperative Nausea and Vomiting in Pediatric Patients

Abstract Background: Postoperative nausea and vomiting (PONV) are common side-effects following strabismus surgery. The present study aimed to compare the effects of different doses of dexmedetomidine (DEX) on PONV incidence in pediatric patients undergoing strabismus surgery. Methods: In this prospective randomized double-blinded study, 126 pediatric patients undergoing strabismus surgery were randomized into one of three groups: Placebo group, normal saline; DEX1 group, 0.3 ug/kg dexmedetomidine, and DEX2 group, 0.5 ug/kg dexmedetomidine. Oculocardiac reflex (OCR) events were recorded during surgery. PONV or postoperative vomiting (POV) was recorded for 24 hours in the ward. Pediatric anesthesia emergence delirium (PAED) scale and emergence agitation (EA) scale were recorded in the recovery room. Results: Intraoperative OCR was significantly reduced in DEX2 group (42%) as compared to that of Placebo group (68%) (p=0.0146). During the first 24 hours post-op, the overall incidence of PONV was significantly lower in DEX2 group (10%) than that of Placebo group (32%) (p=0.0142). There was no significant difference in POV among the three groups. PAED or EA scores among the three groups were similar during recovery time. Conclusion: Dexmedetomidine (0.5 ug/kg) reduced OCR and PONV without lengthening extubation time or recovery time in pediatric patients undergoing strabismus surgery. Trial registration：The trial was prospectively registered before patient enrollment at Chinese Clinical Trial Registry (Clinical Trial Number: ChiCTR1800020176, Date: 12/19/2018).

OBJECTIVE Postoperative nausea and vomiting (PONV) is an extremely common side effect of general anesthesia that is difficult to manage. We tested a hypothesis that an aggressive prophylactic intervention with additional antiemetic drugs will reduce the incidence of PONV in a high-risk pediatric population undergoing adenotonsillectomy. METHODS In this retrospective study, pediatric patients undergoing adenotonsillectomy were screened for their risk factors for PONV. Patients who had 3 or more risk factors were identified as high risk and received either scopolamine patch preoperatively (for patients over 40 kg body weight) or diphenhydramine immediately postextubation in addition to ondansetron and dexamethasone, which are given routinely. Incidences of PONV within the first 60 minutes of a postanesthesia care unit (PACU) stay were collected and analyzed. RESULTS Overall postoperative vomiting rates during the first hour of a PACU stay were 4.3% for the group that was treated with dexamethasone and ondansetron only and 3.9% for the group that was treated with additional antiemetic drugs. Aggressive prophylactic management of PONV did reduce the rate of nausea and vomiting in a group of high-risk patients (p < 0.0001). The postoperative antiemetic drug usage was also decreased during the first 60 minutes of a PACU stay. However, the approach did not reduce the overall rate of PONV for the entire study population (p = 0.1612 for nausea and p = 0.0678 for vomiting). CONCLUSION Aggressive intraoperative management of PONV with additional antiemetic drugs are beneficial in high-risk pediatric population. Intraoperative diphenhydramine usage decreased the rate of PONV. However, preoperative scopolamine patch prevention did not improve PONV, which may be related to the drug's longer onset of action. Our result suggests that current clinical practice is undertreating PONV in pediatric patients receiving general anesthesia.
