经腹部B超评估全麻手术患者膀胱功能性容量恢复的多因素分析

Multivariate Analysis of Bladder Functional Capacity Recovery in Patients Undergoing General Anesthesia by Transabdominal B-Ultrasound

摘要: 目的：通过腹部B超测量手术时长3小时以内的全麻手术患者的膀胱尿量，分析膀胱功能性容量恢复的影响因素，评估采取非侵入性导尿的可行性，促进患者快速康复。方法：选取我院2021年1至2021年6月期间接受全麻手术患者80例，年龄45.3 ± 5.3岁，手术时长2~3小时，通过经腹部B超测定该患者的术前残余尿量、术中1小时膀胱尿量、手术结束后以及苏醒后离PACU膀胱容量，并记录术后首次排尿时间、尿量、年龄及术中输液总量。以患者首次排尿量为膀胱功能性容量恢复的指标，通过多元线性回归分析，评定手术患者不留置导尿管的可行性。结果：膀胱功能的恢复与年龄、输液总量、憋尿时长显著相关，与手术时长、术前残余尿量、术中1小时膀胱尿量、手术结束后以及苏醒后离开PACU的膀胱尿量未显示相关性。所有患者膀胱功能恢复状态良好。结论：手术时长3小时以内的全麻手术患者，经过客观评估膀胱功能，可以选择不侵入性导尿操作，促进术后快速康复。

Abstract: Objective: The bladder and urine volume of patients undergoing general anesthesia surgery within 3 hours of operation was measured by abdominal B-ultrasound, and the factors affecting the recov-ery of functional bladder capacity were analyzed, and the feasibility of non-invasive catheterization was evaluated to promote rapid recovery of patients. Methods: A total of 80 patients who under-went general anesthesia surgery in our hospital from January 2021 to June 2021 were selected, aged 45.3 ± 5.3 years old, and the operation time was 2~3 hours. The urine volume of the bladder in 1 hour, the bladder volume after the operation and after the recovery from the PACU were recorded, and the first urination time, urine volume, age and the total amount of intraoperative infusion were recorded. Using the patient’s first voiding volume as an index of functional bladder capacity recov-ery, multiple linear regression analysis was used to evaluate the feasibility of surgical patients without indwelling catheters. Results: The recovery of bladder function was significantly related to age, total infusion volume, and duration of holding urine, but not to operation time, preoperative residual urine volume, intraoperative bladder urine volume within 1 hour, and bladder urine vol-ume after surgery and after recovery from the PACU. The bladder function of all patients recovered well. Conclusions: Patients undergoing general anesthesia surgery with operation duration of less than 3 hours can choose non-invasive catheterization after objective assessment of bladder function to promote rapid postoperative recovery.
