To evaluate the effect of regional anesthesia and mode of delivery on the function of the urinary bladder. The primary outcome was the time taken for urinary bladder sensation to return following various modes of delivery and analgesia/anesthesia. The secondary outcome was the volume of urine present in the bladder when sensation returned.
The study was conducted at the Birmingham Women's Foundation Trust, Birmingham, UK. A total of 120 postnatal patients were studied between January 2007 and March 2008. The volume of urine in the bladder when sensation first returned was measured by release of a clamp for women fitted with an indwelling catheter, and/or estimated using ultrasound.
The median times for sensation to return to the bladder in patients who had a vaginal delivery without epidural analgesia, vaginal delivery with epidural analgesia, and after elective cesarean delivery under spinal anesthesia were 122 minutes (IQR, 112-136 minutes), 234 minutes (IQR, 202-291 minutes), and 374 minutes (IQR, 311-425 minutes), respectively. The median urine volumes were 144 mL (IQR, 112-192 mL), 200 mL (IQR, 136-336 mL), and 152.5 mL (IQR, 125-270 mL), respectively.
These results should be taken into consideration when formulating a postdelivery bladder care protocol.
评估区域麻醉和分娩方式对膀胱功能的影响。主要结局指标是在各种分娩方式和镇痛/麻醉后膀胱感觉恢复的时间。次要结局指标是感觉恢复时膀胱内的尿量。
该研究在英国伯明翰妇女基金会信托基金进行。共有 120 名产后患者于 2007 年 1 月至 2008 年 3 月间参与研究。对留置导尿管的女性，通过松开夹子测量感觉首次恢复时膀胱内的尿量，或通过超声估计尿量。
未接受硬膜外镇痛的阴道分娩、接受硬膜外镇痛的阴道分娩和选择性脊髓麻醉下剖宫产的患者，膀胱感觉恢复的中位数时间分别为 122 分钟（IQR，112-136 分钟）、234 分钟（IQR，202-291 分钟）和 374 分钟（IQR，311-425 分钟）。膀胱内的尿量中位数分别为 144 毫升（IQR，112-192 毫升）、200 毫升（IQR，136-336 毫升）和 152.5 毫升（IQR，125-270 毫升）。
在制定产后膀胱护理方案时，应考虑这些结果。
