To review and investigate the diagnosis results of local anesthetics (LA) allergy and improve the understanding of LA allergy in clinician. From March 2017 to February 2022, a total of 24 patients were investigated in Allergy Center of West China Hospital,Sichuan University on suspicion of LA allergy. Clinical data and results of skin tests and drug provocation tests (DPT) with the suspected drugs were retrospectively evaluated. The value of standardized diagnostic protocol in the LA allergy were analyzed. The results showed that 24 patients (3 men/21 women) were included with age range from 20 to 74 years. Three cases (12.5%) were positive in previous LA skin tests and proved to be tolerated through standardized tests. Twenty-one patients were initially diagnosed as "LA allergy" because of adverse reactions after previous use of LA, including 20 cases of immediate-type reaction and 1 case of delayed-type reaction. Three cases were considered LA allergy through standardized diagnosis approaches, including skin tests and DPT. One patient was diagnosed with anaphylaxis caused by chlorhexidine. Of the remaining 17 patients, 7 were considered as psychosomatic reactions (29.1%), 3 of sympathetic nervous system conditions (12.5%), 1 of spontaneous urticaria (4.2%), 2 of vasovagal syncope (8.3%), drug side effects (8.3%), skin irritation (8.3%), respectively. In conclusion, true allergic reactions to LA are rare. Through standardized skin tests and DPT, allergy can be ruled out in the vast majority of patients who complain of "LA allergy". For patients who are highly suspected of LA inducing anaphylaxis, other local anesthetics that can be used as safe alternatives should be determined by diagnostic tests according to future needs.

Background Ultrasound-guided continuous thoracic paravertebral block can provide pain-relieving and opioid-sparing effects in patients receiving open hepatectomy. We hypothesize that these effects may improve the quality of recovery (QoR) after open hepatectomy. Methods Seventy-six patients undergoing open hepatectomy were randomized to receive a continuous thoracic paravertebral block with ropivacaine (CTPVB group) or normal saline (control group). All patients received patient-controlled intravenous analgesia with morphine postoperatively for 48 hours. The primary outcome was the global Chinese 15-item Quality of Recovery score on postoperative day 7, which was statistically analyzed using Student's t-test. Results Thirty-six patients in the CTPVB group and 37 in the control group completed the study. Compared to the control group, the CTPVB group had significantly increased global Chinese 15-item Quality of Recovery scores (133.14 ± 12.97 vs. 122.62 ± 14.89, P = 0.002) on postoperative day 7. Postoperative pain scores and cumulative morphine consumption were significantly lower for up to 8 and 48 hours (P < 0.05; P = 0.002), respectively, in the CTPVB group. Conclusion Perioperative CTPVB markably promotes patient's QoR after open hepatectomy with a profound analgesic effect in the early postoperative period.

The opioid epidemic continues to be a serious public health concern. Many have pointed to prescription drug misuse as a nidus for patients to become addicted to opioids and as such, urologists and other surgical subspecialists must critically define optimal pain management for the various procedures performed within their respective disciplines. Controlling pain following penile prosthesis implantation remains a unique challenge for urologists, given the increased pain patients commonly experience in the postoperative setting. Although most of the existing urological literature focuses on interventions performed in the operating room, there are many studies that examine the role of preoperative adjunctive pain medicine in diminishing postoperative narcotic requirements. There are relatively few studies looking at postoperative strategies for managing pain in prosthetic surgery with follow-up past the immediate hospitalization. This review assess the various strategies employed for managing pain following penile implantation through the lens of the current state of the opioid crisis, thus examining how urologists can responsibly treat pain without contributing to the growing threat of opioid addiction.

INTRODUCTION: Adductor canal block (ACB) is hypothesised to provide superior analgesia to femoral nerve block (FNB) for total knee arthroplasty (TKA) while preserving quadriceps strength. METHODS: 30 patients undergoing TKA were randomised to receive either ACB or FNB. Baseline tests of quadriceps strength were performed. Ultrasound-guided blocks with 30 mL of 0.5% ropivacaine were administered before induction of general anaesthesia. Patient-controlled analgesia (morphine) was prescribed for postoperative analgesia. The primary outcome of this prospective, double-blinded, randomised controlled trial was morphine consumption (mean ± standard deviation) in the first 24 hours. Secondary outcomes were pain scores using a numeric rating scale (median and interquartile range [IQR]), quadriceps strength (% of baseline) and functional outcomes at 24 hours and 48 hours postoperatively. RESULTS: There was no statistically significant difference in morphine consumption at 24 hours between the ACB and FNB groups (21 ± 11 mg vs. 20 ± 12 mg; p = 0.85). No statistically significant differences were observed between the ACB and FNB groups in pain scores at 24 hours (at rest: 0 [IQR 0-2] vs. 0 [IQR 0-2]; on movement: 5 [IQR 4-8] vs. 5 [IQR 3-8]) and quadriceps strength (24 hours: 28.8% ± 26.1% vs. 26.8% ± 19.6% of baseline; 48 hours: 31.5 ± 23.1% vs. 33.7% ± 20.1% of baseline). There were also no statistically significant differences in functional outcomes and length of stay. CONCLUSION We found no statistically significant differences in analgesic effects, quadriceps strength or functional recovery postoperatively between ACB and FNB.

OBJECTIVE: To assess the analgesic efficacy of compound lidocaine cream in lumbar puncture of children with leukemia and lymphoma. METHODS: 312 leukemia and lymphoma children necessarily undergone lumbar puncture were divided into compound lidocaine cream (cream) group and compound lidocaine injection (injation) group as control with 156 cases respectively according to the will of inpatient children and their family. For cream group, compound lidocaine cream was smeared on the skin around the lumbar puncture point evenly and covered with sterile and transparent dressing for about one hour before lumbar puncture. Then the cream and transparent dressing were removed and lumbar puncture was performed after regular disinfection. For control group, 2% compound lidocaine was injected as local anesthesia before lumbar puncture. The extent of pain was evaluated by Wong-Baker Faces Pain Rating Scale and FLACC Scale as well as children's physiological indexes (heart rate, breathing, blood pressure). The lumbar puncture success rate and the discomfortableness as well as family satisfaction were recorded by special person. RESULTS: Compared with control group, the incidence of pain and discomfortableness in cream group significantly reduced, and the family satisfaction significantly increased (P＜0.05). There were obviously differences in the physiological indexes (heart rate, breathing, systolic blood pressure) before and after lumbar puncture in control group (P＜0.05). However, the physiological indexes in cream group had no obvious change. There was no difference on the success rate of lumbar puncture between the two methods of anesthesia. CONCLUSION Compound lidocaine cream has significantly analgesic effect which can relieving pain caused by lumbar puncture for children.

OBJECTIVE: To explore the effect of local infiltration of ropivacaine combined with multimodal analgesia with parecoxib for perioperative pain management in patients undergoing pancreaticoduodenectomy. METHODS: This randomized controlled trial was conducted among 98 patients undergoing pancreaticoduodenectomy in the Department of Biliary Surgery of West China Hospital between March, 2017 and August, 2018. The patients were randomized to receive perioperative analgesia with local infiltration anesthesia with ropivacaine combined with multimodal analgesia with parecoxib (experimental group, =50) or postoperative analgesia with dizosin (control group, =48). The regimens for intraoperative anesthesia and postoperative pain relief were identical in the two groups. The differences in NRS pain score, use of pain relief agents, the incidences of adverse reactions to analgesia and wound infection, and the time to first ambulation and first flatus passage after the operation were compared between the two groups. RESULTS: At 12, 24 h, 48 h, 72 h and 7 days after the operation, the patients in the experimental group had significantly lower NRS scores ( < 0.05) than those in the control group. The rate of use of rescue analgesics was significantly lower in the experimental group than in the control group (32% 66.67%, < 0.05); the rate of tramadol hydrochloride use was also significantly lower in the experimental group ( < 0.05). Compared with those in the control group, the patients in the experimental group showed a significantly lower total incidence of adverse reactions (22% 54.17%, < 0.05) as well as a lower incidence of nausea and vomiting ( < 0.05), an earlier time of first ambulation and first flatus passage after the operation ( < 0.05), and a shorter postoperative hospital stay ( < 0.05). CONCLUSIONS In patients undergoing pancreaticoduodenectomy, local infiltration of ropivacaine combined with multimodal analgesia with ropivacaine can effectively relieve perioperative pain, reduce the use of relief analgesics, lower the incidence of adverse reactions, and promote the recovery after the surgery.
