ObjectiveTo analyze the postoperative drainage volume and its influencing factors in lumbar posterior surgery.MethodsA total of 158 patients undergoing lumbar posterior surgery in West China Hospital, Sichuan University between October 2018 and June 2019 were retrospectively enrolled in this study. The data about general information and perioperative drainage were collected retrospectively according to recording tables and analyzed by SPSS (version 22) software. The drainage volume was presented with median (lower quartile, upper quartile).ResultsThe final average drainage volume was 360 (200, 650) mL, and the length of time for drainage tube placement was from 9 to187 hours with the median (lower quartile, upper quartile) of 61 (40, 86) hours. The result of multiple linear regression showed that immediate drainage volume when returning to the ward [non-standardized partial regression coefficient (b)=0.268, 95% confidence interval (CI) (0.191, 0.345), P<0.001], length of time for drainage tube placement [b=0.554, 95%CI (0.338, 0.769), P<0.001], intra-operative bleeding volume [b=0.161, 95%CI (0.044, 0.277), P=0.007], and surgical methods [Method 3 as the reference, Method 1: b=0.599, 95%CI (0.369, 0.828), P<0.001; Method 2: b=0.574, 95%CI (0.336, 0.812), P<0.001] were the main factors affecting the final drainage volume.ConclusionsThe final drainage volume of lumbar posterior surgery is so large that it should be paid attention to. It is also necessary to take effective interventions according to different surgical methods, intraoperative bleeding, immediate drainage when returning to the ward, length of time for drainage tube placement, and other different circumstances to reduce the drainage to achieve enhanced recovery after surgery.
ObjectiveTo investigate the status of urination in post-spineoperative (cervical thoracic and lumber verteb) patients under the enhanced recovery after surgery (ERAS) mode.MethodsPatients who were admitted to the West China Hospital of Sichuan University from October 2018 to February 2019 were enrolled. The urination status of the patients was collected by using questionnaires. All patients were divided into normal urinating group, induced urinating group and catheterization group according to their urination status after returning to the ward.ResultsA total of 106 patients were included, including 78 (73.6%) who urinated smoothly [the first urinating time (72.18±36.33) min], 20 (18.9%) who urinated after induction [the first urinating time (81.50±41.68) min], and 8 (7.5%) who received catheters after induction failure [the first urinating time (162.50±84.52) min]. The different operation, operation time, position of urination, and postoperative pain degree affecting the placement of urethral catheter differed from each other significantly (P<0.05). Among the three groups, the differences were statistically significant in operation time, operation methods, position of urination (except for the induced urination group vs. catheterization group) and postoperative pain degree (except for the induced urination group vs. catheterization group) in pairs (P<0.05). There was no significant difference in other factors among three groups in pairs (P>0.05).ConclusionsMost post-spineoperative patients can autonomously urinate without catheter under the ERAS mode, which bases on operation methods, operation time, and the first urinating posture after the surgery. Early attention should be paid to patients with dysuresia to promote their early rehabilitation.
