Background. The objective of this study was to observe the effects of butorphanol as an adjuvant to ropivacaine for the adductor canal block (ACB) on postoperative analgesia in patients undergoing total knee arthroplasty (TKA). Methods. Seventy-four patients undergoing TKA were included and randomly divided into two groups: Group BR received 20 ml of 0.33% ropivacaine plus 1 mg butorphanol and Group R received 20 ml of 0.33% ropivacaine plus 1 ml normal saline for ultrasound-guided adductor canal blocks. The primary outcomes were the duration of the sensory block and the pain visual analogue scale (VAS), and secondary outcomes included the number of PCIA attempts (patient-controlled intravenous analgesia) and the time to first pressing and rescue analgesia. Other outcomes included knee active range of motion (ROM), quadriceps strength, the time to first mobilization, the duration of postoperative hospital stay, Knee Society Score (KSS), and postoperative complications. Results. Since two patients in each group rejected postoperative assessments, 35 patients were included in each group. Compared with Group R, Group BR had longer duration of sensory blocks (18.42 ± 3.46 vs. 15.36 ± 2.29 h, p < 0.01 ) and lower postoperative pain scores within 24 hours at rest and within 12 hours with activity ( p < 0.01 ). The number of PCIA attempts decreased within 48 hours after surgery (4.5 ± 1.2 vs. 7.8 ± 1.5 times, p < 0.01 ), and the time to first pressing was later (20.31 ± 2.59 vs. 16.25 ± 2.31 h, p < 0.01 ). In addition, Group BR had bigger knee ROM at within 24 hours after the operation than Group R (68.37 ± 4.70°vs. 59.21 ± 6.41,85.67 ± 5.17 vs. 74.37 ± 4.68°, 97.62 ± 5.43 vs. 84.18 ± 4.49°, p < 0.01 ). There was no significant difference between the two groups ( p > 0.05 ) in terms of rescue analgesia, quadriceps strength, the time to first mobilization, the duration of postoperative hospital stay, the KSS function scores, and postoperative complications. Conclusions. Butorphanol plus ropivacaine ultrasound-guided adductor canal block can prolong the duration of sensory block, relieve early postoperative pain, and improve the range of motion of the knee joint, without affecting the occurrence of postoperative complications.

Objective:To evaluate the association between sleep health characteristics and kidney stones.Methods:We performed a cross-sectional analysis using data from National Health and Nutrition Examination Survey (NHANES 2007-2008). The primary exposures were self-reported sleep duration, obstructive sleep apnea and sleep difficulty. The primary outcome was nephrolithiasis. We examined the association between sleep health characteristics and kidney stones using multivariable logistic regression models and reported odds ratios (ORs).Results:After fully multivariate adjustment, obstructive sleep apnea is positively associated with the risk of kidney stones (OR=1.34, 95% CI:1.10–1.63, P=0.0037). Then, the sleep difficulty group had a 1.49-fold increased risk of kidney stone (95% CI:1.23–1.80, P < 0.0001). However, insufficient (< 7 Hours/Night) sleep seems not to be associated with kidney stone (OR=1.08, 95%CI: 0.90-1.29, P=0.3992).Conclusions:After controlling for known risk factors, obstructive sleep apnea and sleep difficulty were associated with an increased likelihood of kidney stone incidence.
