RESUMO
Background and Aims: Motor-sparing analgesia after total knee arthroplasty (TKA) is crucial. The primary endpoint was the postoperative visual analogue scale (VAS) score after triple injection peri-sartorius (TIPS) block after TKA. Secondary endpoints were postoperative morphine consumption, 24-h postoperative ambulation distances and the degrees of active knee extension. Methods: After general anaesthesia or spinal anaesthesia administration and before surgical incision, 80 patients undergoing TKA were randomised into group TIPS (received ultrasound-guided TIPS block where 40 ml 0.25% bupivacaine and 4 mg dexamethasone were injected: 10 ml at the distal femoral triangle, 10 ml above the sartorius and 20 ml at the distal adductor canal) and group FNB (femoral nerve block; received ultrasound-guided FNB with 20 ml 0.25% bupivacaine mixed with 4 mg dexamethasone). Postoperative pain score was noted and compared. Results: Dynamic VAS scores were lower in the TIPS group than in FNB, while the resting VAS scores were not significantly different. Mean (standard deviation [SD]) postoperative morphine consumption was 5.82 (2.47) mg in the TIPS group (95% confidence interval [CI] 5.03,6.61) versus 9.87 (2.99) mg in the FNB group (95% CI 8.91,10.83). Ambulation distances and active postoperative knee extension in the TIPS group showed greater significance than in the FNB group (TIPS: 18.0 [7.37] m, 95% CI 15.64,20.35] vs. FNB: 8.95 [5.93] m, 95% CI 7.05,10.84) and (TIPS: 52.12 [16.39], 95% CI 46.88,57.33 vs. FNB: 26.05 [11.10], 95% CI 22.501,29.59). Nausea was more evident in FNB patients. Conclusion: TIPS block provides superior analgesia than FNB with motor sparing of the quadriceps after TKA.
RESUMO
BACKGROUND: Acetabular fracture surgery can cause severe postoperative pain. A combined lumbar erector spinae plane block and paraspinous sagittal shift quadratus lumborum block may augment analgesia. METHODS: Fifty two patients undergoing posterior column acetabular surgery were divided into: Group Single puncture combined lumbar Erector spinae and Quadratus lumborum block (SEQ), patients who received SEQ block before anesthesia; and Group morphine (MOR), those who received general anesthesia (GA) and morphine. RESULTS: Demographic characteristics were comparable. The heart rate and mean arterial blood pressure were significantly lower in the SEQ group than in the MOR group between 60 and 180 min intraoperatively (P < 0.001). Postoperative resting and dynamic visual analogue scale scores in the SEQ group were significantly lower than those in the MOR group at all studied periods (P = 0.022-0.001), except at 20 and 24 h postoperatively. Fentanyl was required in all MOR group patients at a mean dose of 110.0 ± 28.42 µg while 18 patients required fentanyl in SEQ group at a mean dose of 60.55 ± 25.54 µg. Postoperative morphine consumption was significantly less in SEQ group (6.33 ± 2.37 mg) than MOR group (17.0 ± 2.55 mg). Postoperative nausea and vomiting were recorded in eight and four patients in MOR and SEQ group, respectively. No complications associated with the block technique were observed. CONCLUSIONS: The SEQ block reduces the postoperative opioid consumption and provides stable intra and postoperative hemodynamics without observed complications in posterior column acetabular surgery.
RESUMO
Background and Aim: Ultrasound (US) guided regional analgesia is a safe and effective method in providing perioperative analgesia in pediatrics with a high success rate rapid onset and fewer side effects. The aim of this study was to compare the efficacy of US-guided caudal block versus US-guided peripheral nerve blocks (femoral and sciatic nerve blocks) in providing perioperative analgesia in pediatrics undergoing unilateral lower limb surgery. Methods: Children aged 1-12 years scheduled for unilateral lower limb surgery during the period from January 2020 to December 2021 were randomly allocated into two groups. Group C where pediatrics received US-guided caudal block, while in group P, pediatrics received US-guided femoral and sciatic nerve blocks after the induction of general anesthesia (GA). The primary aim was to compare the postoperative pain (evaluated by the COMFORT pain score) between the two groups. Secondary aims were to compare perioperative opioids used parents' satisfaction and occurrence of side effects. Results: Pediatrics who underwent unilateral lower limb surgeries were allocated into two groups (group C and group P). There was no significant difference between patients' baseline characteristics and the postoperative pain score at 2, 4, 16, and 20 h.' However there was a statistical significance at 6, 8, 12, and 24 h postoperatively, frequency of analgesia as well as the total postoperative dose of opiates (nalbuphine). Time to first analgesic (nalbuphine) requirement was significantly less in group C with a mean of (9.6±2.9 h) than in group P with a mean of (15.1±3.5 h). Parents of children in group P were more satisfied than those in group C with no recorded complications for both techniques. Conclusion: US-guided lower limb peripheral nerve block is a simple and safe method to provide adequate and more prolonged analgesia compared to US-guided caudal block for lower limb surgeries in pediatrics.
