Postoperative pain management in orthopaedic patients: no differences in pain score, but improved stress control by epidural anaesthesia

Background and objectivesBuprenorphine is a partial µ-receptor agonist resistant to displacement from receptors by conventional opioids, which can block the effect of conventional opioids and may interfere with postoperative pain management. We aimed to quantify perioperative opioid use in patients receiving transdermal buprenorphine (TdBUP).MethodsWe identified patients receiving TdBUP who underwent surgery between 2004 and 2016. To compare opioid requirements (intravenous morphine equivalents (IV-MEq)), we constructed a matched study, matching each TdBUP patient with two opioid-naive patients by sex, age, and type of anesthesia and procedure.ResultsNineteen unique patients underwent 22 procedures while receiving TdBUP. Total (IQR) amounts of IV-MEq (intraoperative, recovery room, and 24 hours after recovery-room discharge) were 98 (63, 145) and 46 (30, 65) mg IV-MEq for TdBUP and opioid-naive patients, respectively (p<0.001). Postoperative IV-MEq requirements were 54 (38, 90) and 15 (3, 35) mg for TdBUP and opioid-naive patients, respectively (p<0.001). Among TdBUP patients, higher preoperative doses of TdBUP were associated with greater postoperative opioid requirements (p=0.02). Specifically, patients with a 20 µg/hour TdBUP patch required 133.8 mg IV-MEq more postoperatively than patients with a 5 µg/hour patch (p=0.002). Following discharge from the recovery room, 17 (77%) TdBUP patients and 15 (34%) opioid-naive patients reported severe pain (OR 6.6 (95% CI 2.0 to 21.3); p<0.001; adjusting for baseline pain score, 5.0 (95% CI, 1.4 to 17.8); p=0.01).ConclusionsAnalgesic management for patients receiving TdBUP therapy must account for increased opioid needs, and greater preoperative doses of TdBUP were associated with greater postoperative opioid requirements.

Objective: This study was designed to compare the mean pain score with bupivacaine versus tramadol plus bupivacaine in patients undergoing surgery under general anesthesia. Randomized Controlled Study. Anesthesia department of SIMS medical college/Services Hospital, Lahore. Duration is 13 months from 20th August2017 till 24th September 2018. Method: 80 patients aged 20-60 years of ASA I & II status, undergoing elective surgery were selected. Patients were randomly divided into two groups (Group A and B) of 40 each, using random numbers table. An epidural catheter was placed at L3-L4 intervertebral level. Group A was given 30 ml of 0.125% bupivacaine and Group B was given 25mg Tramadol plus 0.125% bupivacaine mixture in the same volume. General anesthesia was induced with IV Propofol 2mg/kg and atracurium 0.5mg/kg. After recovery from anesthesia, patients were shifted to HDU. Post-operative pain was assessed using the 10-point VAS score. Injection nalbuphine 0.1mg/kg was given as rescue analgesic when VAS score became more than 4. Results: The mean age of patient in Group A was 37.5 ± 9.1 years and 38.6 ± 7.0 years in Group B. Mean BMI in Group A was 33.2 ± 4.3 and 32.2 ± 4.2 in Group B. The mean pain score after 12 hours of surgery was 3.6 ± 0.8 in Group A and 1.5 ± 0.9 in Group B, p value was significant. Conclusion: Thus, the present study concludes that epidural administration of tramadol as adjuvant with bupivacaine is more effective in postoperative pain relief as compared to bupivacaine alone.

Subcutaneous Sumatriptan

OBJECTIVESumatriptan, a serotonin receptor agonist, has been used in the management of primary headache disorders and has been shown to affect trigeminal dural afferents. There is limited literature on the safety and efficacy of sumatriptan for postcraniotomy pain management. This study aimed to identify whether subcutaneous sumatriptan is a safe and efficacious pain management strategy after elective craniotomy.METHODSThe authors retrospectively reviewed patients who underwent supratentorial or suboccipital craniotomy between 2016 and 2019 that was performed by a single provider at a single institution to identify patients given subcutaneous sumatriptan in the postoperative period. Pain scores and intravenous and oral opioid use were compared in patients with (n = 15) and without (n = 45) sumatriptan administration.RESULTSPatients with and without sumatriptan administration had no significant differences in baseline characteristics or surgery type. There were no sumatriptan-related complications. The average pain score decreased from 3.9 to 1.3 within 1 hour after sumatriptan administration (p = 0.014). In both adult and pediatric patients there was decreased postoperative pain (adults: pain score of 1.1 vs 7.1, p < 0.001; pediatric: 1.1 vs 3.9, p = 0.007) within the first 48 hours. There were decreases in intravenous opioid use, length of intravenous opioid use, maximum dose of intravenous opioid used, oral opioid use, length of oral opioid use, and maximum dose of oral opioid used in both adult and pediatric patients.CONCLUSIONSThe authors identified subcutaneous sumatriptan as a safe and efficacious tool for postoperative pain management after craniotomy. Large multicenter randomized controlled studies are needed to further evaluate the specific role of sumatriptan in postoperative pain management after craniotomy.
