Analysis of influencing factors of postoperative nausea and vomiting in patients undergoing microvascular decompression
Objective To explore the influencing factors of postoperative nausea and vomiting(PONV)in patients undergoing after microvascular decompression(MVD).Methods A total of 385 patients who underwent MVD in Xuanwu Hospital of Capital Medical University from January 4,2022 to March 25,2023 were selected,and were devided into PONV group(203 cases)and non-PONV group(182 cases)according to whether PONV occurred within 24 hours after operation.The influencing factors of PONV in MVD patients was analyzed by multivariate logistic regression.Results Among the 385 patients,there were 164 males and 221 females,aged from 24 to 80 years,with an average age of(56.3±11.0)years.There were 148 cases of facial spasm and 237 cases of trigeminal neuralgia.A total of 203 of PONV occurred within 24 hours after operation,the incidence rate was 52.73%.Multivariate logistic regression analysis showed that patients with no smoking history(OR = 0.290,95%CI:0.161-0.521,P = 0.000),vascular and nerve adhesions(OR = 2.381,95%CI:1.115-5.084,P = 0.040),more responsible blood vessels(OR = 2.426,95%CI:1.132-5.198,P = 0.023),more pads used(OR = 1.665,95%CI:1.187-2.335,P = 0.003),and longer anesthesia time(OR = 1.006,95%CI:1.001-1.012,P = 0.031),without prophylactic use of antiemetics(OR = 0.535,95%CI:0.300-0.953,P = 0.034),the use of sevoflurane(OR = 33.315,95%CI:14.102-78.707,P = 0.000),the higher the amount of postoperative analgesic sufentanil used(OR = 1.029,95%CI:1.010-1.049,P = 0.003),were more prone to have PONV.Conclusions The incidence of PONV in MVD patients is high,and surgical operation,patients'own factors,intraoperative anesthesia and postoperative analgesia can all lead to PONV.In the case of a certain duration of MVD surgery,preventive use of antiemetics,reducing the use of inhaled narcotic drugs during the operation and reducing the use of opioids after the operation can prevent the occurrence of PONV.
