Background: Total knee arthroplasty (TKA) is concerned as a severe postoperative pain procedure. Intrathecal morphine provides good analgesia but has many side effects such as nausea, vomiting, pruritus and respiratory depression. Appropriate postoperative pain control strategy with lower side effect is still challenging. We combined periarticular injection(PI) as a multimodal analgesia with intrathecal morphine in order to decrease intrathecal morphine dosage and lower side effects. Objective: To determine side-effect profiles and efficacy of 0.1 mg and 0.2 mg intrathecal morphine combine with PI in primary unilateral TKA. Material and method: In this prospective, double-blinded, randomized controlled trial. Patients undergoing TKA were recruited from April 2018 to April 2019. All patients were randomized into 3 groups. M 0 (n=32), M 1 (n=36)and M 2 (n=34) represent no intrathecal morphine, 0.1 mg and 0.2 mg intrathecal morphine respectively. All Group received same regimen of PI as a multimodal analgesia and same postoperative pain control protocol. Results: Patients in group M 2 had more nausea or vomiting side effects compared to group M 1 in early postoperative 4 hours(77.1% and 51.4%) with statistical significant(p<0.05) and also required 2 antiemetic drug to relieve symptoms (4.7% and 2.3%) with statistical significant ( p<0.05). No difference in postoperative pain score, rescue analgesic drug consumption ,pruritic score, sedation score, respiratory depression and orthopedic outcomes such as straight leg rising time and maximum active knee flexion between M 1 and M 2 groups. Conclusion: Lower intrathecal morphine dosage (0.1 mg) combine with periarticular injection in primary unilateral total knee arthroplasty provide similar postoperative pain control as standard intrathecal morphine dosage(0.2 mg) combine with periarticular injection with lower rates and severities of nausea and vomiting in first postoperative 4 hours.

Introduction: Caudal block is a routinely performed analgesic and anaesthetic technique in paediatric population undergoing various infra-umbilical surgeries. Various adjuvants have been used along with local anaesthetics like ropivacaine in single-shot caudal block for enhancing postoperative analgesia in paediatric infra-umbilical surgeries. Aim: To evaluate the efficacy of dexamethasone used as an adjuvant to 0.2% ropivacaine in caudal block for postoperative analgesia in paediatric patients. Materials and Methods: This was a randomised doubleblinded controlled study conducted on 80 paediatric patients (8 months-8 years), with American Society of Anesthesiologists (ASA) physical status I or II undergoing various infra-umbilical surgeries,at a tertiary care teaching institute from April 2019 to September 2019. These total subjects were randomly allocated into two groups. GroupR (n=40) administered 0.2% ropivacaine (1 mL/kg) while GroupRD (n=40) administered 0.2% ropivacaine (1 mL/kg) with dexamethasone (0.1 mg/kg) in caudal block. The duration of analgesia, postoperative pain scores (Face Legs Activity Cry Consolability (FLACC) score), rescue analgesic consumption in 24 hours, haemodynamic changes and side-effects were noted. The rescue analgesic (paracetamol 15 mg/kg oral) was given whenever FLACC ≥4. Standard qualitative and quantitative tests (unpaired student t-test, Chi-square test) were used to analyse and compare the results obtained. Results: The mean duration of analgesia was significantly longer in Group RD (745.21±146.91 min) as compared to GroupR (440.38±76.44 min); (p-value <0.001). The significantly lower FLACC pain scores were noted in patients in Group RD compared to Group R; (p-value <0.05). The rescue analgesic consumption was significantly lesser in Group RD in terms of requirement of number of doses of rescue analgesic than in Group R; (p-value <0.05). No significant haemodynamic changes or side-effects were observed in both groups; (p-value >0.05). Amongst postoperative complications noted, fever was observed in 1 patient (3.33%) and PONV in 2 patients (6.66%) in Group R. None complications were observed in the patients of RD group. Conclusion: Dexamethasone (0.1 mg/kg) was found to be safe and effective adjuvant to 0.2% ropivacaine for caudal block in children undergoing various infra-umbilical surgeries.

Purpose: Evaluate the reliability of the early functional recovery and postoperative pain control using adductor canal block (ACB) compared with that using femoral nerve block (FNB) in patients undergoing total knee replacement (TKR). Patients and Methods: A total of 80 patients scheduled for TKR were randomly and blindly distributed into two groups (40 patients each). Group A received ACB and group F received FNB. The early quadriceps strength, range of motion and pain control were assessed after surgery during the first 48[Formula: see text]h. Results: Patients in group F had significantly less quadriceps power postoperatively than those in group A. There were no significant differences between the two studied groups as regard ambulation, range of motion and pain estimation. Conclusion: Since both blocks have comparable analgesic effect and opioid consumption rates, the increased quadriceps muscle strength and ability to ambulate on the first postoperative day is the driving factor in selecting the ACB. With the findings discussed in our study and in literature, an ACB is a viable option in place of a FNB in patients undergoing a total knee arthroplasty. Additional large participant randomized controlled studies should be conducted to further discover the benefits of an ACB in patients undergoing a total knee arthroplasty.

Background and methods: Intrathecal opioids (ITOs) have been used for decades to control postoperative pain. Intrathecal opioid dosing is limited, however, by opioid-related side effects, most importantly respiratory depression. To overcome these limitations, we combined intrathecal morphine with a continuous intravenous (IV) postoperative naloxone infusion to control opioid-related side effects. The purpose of this study is to document the efficacy and safety of high-dose intrathecal morphine combined with postoperative naloxone infusion to provide postoperative analgesia after major surgery. After IRB approval, a retrospective chart analysis was performed on 35 patients who had a radical prostatectomy from 2004 to 2006. All patients received a single injection of ITOs before anesthesia, a typical general anesthestic, followed by naloxone infusion at 5 μg/kg/h started 1 hour post-ITOs and continued for 22 hours postoperatively. The following information was collected: patient age, height, weight, anesthesia technique/time, and dose of ITOs given. Postoperative pain relief was assessed for 48 hours using the Visual Analog Score (VAS) for pain (0, no pain; 10, worst pain), perioperative opioid use, NSAID consumption, and ability of patient to ambulate. The safety of this novel treatment was assessed with opioid-related side effects and vital signs. All data are reported as mean (SD).Results: Mean ITOs given were morphine 1.3 (0.3) mg combined with fentanyl 56 (9) μg. The intrathecal morphine dose ranged from 0.8 to 1.7 mg. The mean worst pain VAS in the first 12 hours postoperatively was only 1.0 (1.7). The first NSAID dose was given 6.6 (3.1) hours post-ITOs. The first opioid on the floor was given an average of 22.6 (14.5) hours post-ITOs. A mean of only 5.7 (12.3) morphine equivalents were required on postoperative day 1 (POD 1). On POD 2, the mean worst pain VAS was only 2.6 (2.2) with only 5.7 (6.2) morphine equivalents needed to provide pain relief. On POD 1, 25 patients required no additional opioids for their entire hospital stay. Overall, 11 of 35 patients did not require any additional postoperative opioids. Thirtyfour patients (97 percent) were able to ambulate in the first 12 hours postoperatively. No opioid-induced respiratory depression was observed. Opioid-related side effects (pruritus, nausea) were infrequent and minor.Conclusions: High-dose ITOs combined with postoperative IV naloxone infusion provided excellent analgesia for radical prostate surgery. IV naloxone infusion appeared to control opioid side effects without diminishing the analgesia. No serious adverse effects were noted.

Background: Dexmedetomidine and midazolam both modulate spinal analgesia by different mechanisms, and yet, no human studies are available to compare them for postoperative analgesia after neuraxial administration. Objectives: We investigated the addition of dexmedetomidine or midazolam to intrathecal bupivacaine on the duration of effective analgesia and clinical safety profile. Study Design: Prospective, randomized, double blind, placebo controlled study. Setting: University teaching hospital. Methods: The study cohort included a consecutive and prospective series of patients, referred for endourological procedures. The patients were randomly allocated into 3 groups (20 patients each) to receive intrathecally 3 mL of 0.5% hyperbaric bupivacaine in combination with 5 mcg of dexmedetomidine (dexmedetomidine group), 1 mg of midazolam (midazolam group) or 0.5 mL of 0.9% saline (control group). The groups were compared to the regression time of sensory block, duration of effective analgesia (defined as the time interval between administration of intrathecal drug to the time of first analgesic request or a numeric rating scale ≥ 4.0), sedation score, and side effects in the first 24 hours. Statistics: One way-ANOVA, Kruskal Wallis test, and Chi-square test (χ2), significance level: P < 0.05. Results: The duration of effective analgesia (time to first analgesic request) was significantly prolonged in the dexmedetomidine group (286 ± 64 minutes, P < 0.01) when compared with midazolam group (236.9 ± 64.9 minutes) and the control group (212.7 ± 70.2 minutes). Pairwise comparisons among the 3 groups with Bonferroni adjustment revealed that patients from the dexmedetomidine group were more sedated in comparison to the midazolam and control groups at the end of the first 15 minutes after intrathecal injection [χ2 (2) = 7.157, P = 0.028], with a mean rank sedation score of 35.58 for dexmedetomidine, 25.00 for midazolam, and 30.93 for control. No significant differences in the side effects were observed during the study period. Midazolam did not lengthen the time of the two segment sensory regression or the time to first request analgesia. Limitation: The study cannot be extrapolated to muscle cutting surgeries under spinal anaesthesia. Conclusions: The addition of dexmedetomidine (5 mcg) to 3 mL of intrathecal hyperbaric bupivacaine (0.5%) significantly prolongs the duration of effective analgesia in comparison to 1 mg midazolam or placebo (0.9% normal saline) with a comparable incidences of side effects.

Introduction/Objective. This prospective, randomized study was done to determine the efficiency and safety of the administration of intrathecal morphine chloride combined with the local anesthetic levobupivacaine given to female patients subjected to hysterectomy to ensure postoperative analgesia. Methods. The study sample consisted of 50 patients who were to undergo hysterectomy with adnexectomy and they were divided into two groups of 25 each. The patients in group A were given the combination of 0.3 mg of morphine chloride with 1.7 ml of 0.5% levobupivacaine immediately before the surgery, whereas the patients in group B were intravenously administered 5 mg of morphine chloride before the end of surgery, and after the surgery at certain time intervals. The postoperative pain was assessed at the first, sixth, 12th, and 24th hour by Numeric Rating Scale (NRS). Side effects, such as nausea, vomiting, itching and respiratory depressions were followed as well. Results. The postoperative pain was less expressed at any time interval both at rest and on exertion in group A (p < 0.001) and therefore the need for additional analgesia was less in group A (p < 0.001). The subjective feeling of satisfaction with postoperative analgesia was statistically significant in group A (p < 0.001). Conclusion. Intrathecal administration of morphine chloride combined with levobupivacaine ensures better postoperative analgesia after hysterectomy than intravenous morphine chloride, their side effects being equally frequent..
