BACKGROUND
Postoperative pain management using nonsteroidal anti-inflammatory drugs with no narcotic-attributed adverse effects, such as respiratory depression, nausea, and vomiting, is still the subject of extensive research. However, concerns about bleeding and nephrotoxicity have limited routine use.
OBJECTIVES
The present trial aimed to compare the effects of ketorolac/apotel and meperidine on postoperative pain relief in patients undergoing thoracotomy.
METHODS
This randomized controlled trial enrolled 122 patients who were candidates for right thoracotomy. The patients were randomly divided into two groups that received ketorolac (30 mg)/apotel (1 g) or meperidine (0.5 - 1 mg/kg) at the beginning of recovery, respectively. This study assessed the Numeric Rating Scale pain score immediately and 30 and 60 minutes after the surgery in the recovery room, blood pressure, oxygen saturation (SpO), sweating, and pulse rate.
RESULTS
The average pain score at recovery time was significantly lower in the ketorolac/apotel group (2.06 ± 1.40) than in the meperidine group (2.76 ± 1.61) (P = 0.011). In contrast to the ketorolac/apotel group, an increasing trend was observed in pain scores in the meperidine group throughout the time sequence (P < 0.05). However, a slight non-significant increase was also observed in the ketorolac/apotel group. No statistical differences were observed in blood pressure (P = 0.826), SpO (P = 0.826), and pulse rate (P = 0.811) between the two study groups.
CONCLUSIONS
This study provides support that the combination of ketorolac/apotel offers a slightly superior analgesic effect for patients undergoing thoracotomy, compared to meperidine. Pain management is crucial during recovery, and the current study's findings suggest that administering ketorolac/apotel provides effective analgesia during recovery after thoracic surgery.

Randomized Controlled Trial
BACKGROUND Caudal block is widely regarded as the top choice for multimodal analgesia in children undergoing urological surgeries, particularly circumcision. This study investigates the efficacy of caudal block and the necessity of rescue analgesia in circumcision surgeries. MATERIAL AND METHODS A prospective, single-blind study was conducted at Ordu University Training and Research Hospital from December 1, 2022, to July 1, 2023. The study randomly divided ASA class I-II children aged 1-12 years into 3 groups for circumcision surgery. Group C received only caudal block. Group CP received caudal block with 10 mg/kg intravenous paracetamol. Group CM received caudal block with 1 mg/kg intravenous meperidine. In each case, a caudal block was administered using 0.5 ml/kg of 0.125% bupivacaine under ultrasound guidance. The primary outcome of the study was total analgesic consumption; the secondary outcomes were pain scores and time to first analgesic administration. Pain severity was evaluated using FLACC and Wong-Baker scores at 0, 1, 4, and 24 h. RESULTS A total of 120 patients, 40 patients in each group, were included in the study. A significant difference was detected among all 3 groups in the Wong-Baker pain score (24th hour) (P<0.001). The FLACC and Wong-Baker pain scores did not differ significantly in the other time frames. The time of the first rescue analgesia and the total amount of analgesic taken in the first 24 h were the same for both groups (P=0.408 and P=0.238). CONCLUSIONS The addition of paracetamol or meperidine to caudal block does not enhance the quality of analgesia.

: The purpose of the study was to investigate the role of adrenaline (ADR), noradrenaline (NDR), and cortisol in the pathogenesis of the analgesic potency, duration, and epilepsy-like toxic effect of meperidine. : The experimental animals were separated into 11 groups of six rats. In the meperidine (MPD) and metyrosine + meperidine (MMPD) groups, paw pain thresholds were measured before and after the treatment between the first and sixth hours (one hour apart). In addition, ADR and NDR analyses were performed before and after the treatment, between the first and fourth hours (one hour apart). For the epilepsy experiment, caffeine, caffeine + meperidine, and caffeine + meperidine + metyrapone groups were created, and the treatment was applied for 1 day or 7 days. Groups were created in which caffeine was used at both 150 mg/kg and 300 mg/kg. Epileptic seizures were observed in epilepsy groups, latent periods were determined, and serum cortisol levels were measured. : In the MPD group, pain thresholds increased only at the first and second hours compared to pre-treatment, while ADR increased at the third hour, leading to a decrease in pain thresholds. In the MMPD group, the increase in paw pain thresholds at 1 and 6 h was accompanied by a decrease in ADR and NDR. In the caffeine (150 mg/kg) + meperidine group, 1-day treatment did not cause epileptic seizures, while seizures were observed and cortisol levels increased in the group in which treatment continued for 7 days. When cortisol levels were compared between the group in which caffeine (300 mg/kg) + meperidine + metyrapone was used for 7 days and the animals receiving caffeine (300 mg/kg) + metyrapone for 7 days, it was found that cortisol levels decreased and the latent period decreased. : The current study showed that if serum ADR and cortisol levels are kept at normal levels, a longer-lasting and stronger analgesic effect can be achieved with meperidine, and epileptic seizures can be prevented.

The aim of this study was to compare the intra and postoperative analgesic effects of sacrococcygeal epidural levobupivacaine with those of lumbosacral levobupivacaine in feline ovariohysterectomy. Thirty-six cats were premedicated with intramuscular acepromazine (0.05 mg/kg) and meperidine (6 mg/kg). Anesthesia was induced with intravenous propofol and maintained with isoflurane in oxygen. The cats were randomly assigned one of the three treatments receiving 0.33% levobupivacaine (0.3 mL/kg) into the sacrococcygeal (S-C group, n=12) or lumbosacral (L-S group, n=12) epidural space, or the same volume of 0.9% saline solution into one of the epidural approaches (Control group, n=12). Intraoperatively, cardiorespiratory variables, end-tidal isoflurane concentration (FE´ISO), and fentanyl requirements were recorded. Postoperative pain was assessed by the UNESP (Universidade Estadual Paulista)-Botucatu multidimensional composite pain scale and the Glasgow feline composite measure pain scale up to 8 hr post-extubation. Morphine was administered as rescue analgesia. Overall FE´ISO and fentanyl requirements were lower in the L-S and S-C compared to the Control (P=0.002-0.048, respectively). There was no significant difference in the cardiorespiratory variables during anesthesia, postoperative pain and rescue analgesia among groups. The time to standing after anesthesia was prolonged in the L-S and S-C groups than in the Control (P<0.001). Lumbosacral and sacrococcygeal epidural levobupivacaine resulted in similar decreases in isoflurane requirements and intraoperative fentanyl supplementation in the cats, with no postoperative benefits.

Croatian Medical Journal Aug 2023To investigate whether IV lidocaine improves emergence, early recovery, and late recovery after general anesthesia in women who undergo breast surgery. (Randomized Controlled Trial)
Randomized Controlled Trial
Effects of an intravenous lidocaine bolus before tracheal extubation on recovery after breast surgery - Lidocaine at the End (LATE) study: a randomized controlled clinical trial.
AIM
To investigate whether IV lidocaine improves emergence, early recovery, and late recovery after general anesthesia in women who undergo breast surgery.
METHODS
Sixty-seven women with American Society of Anesthesiologists physical status I-II, scheduled for breast surgery were randomized to receive an IV lidocaine 1.5 mg/kg bolus (n=34) or saline placebo (n=33) before tracheal extubation. Anesthesia was induced with thiopental, vecuronium, and fentanyl, and maintained with sevoflurane~1 MAC and 50% nitrous-oxide in oxygen. No postoperative nausea and vomiting (PONV) prophylaxis was given. Time to extubation, bucking before extubation, and quality of emergence, as well as early and late recovery (coughing post-extubation, sore throat, PONV, and pain scores) within 24 hours postoperatively were evaluated. Diclofenac and meperidine were used for the treatment of pain and metoclopramide for PONV.
RESULTS
The groups did not significantly differ in demographics, intraoperative data, or PONV risk scores. Extubation was~8 minutes in both groups. Patients who received IV lidocaine had significantly smoother recovery, both statistically and clinically; they had better extubation quality scores (1.5 [1-3] vs 3 [1-5], P<0.001), less bucking before extubation (38% vs 91%, P<0.001), less coughing after extubation (at 1 min 18% vs 42%, P=0.026; and at 24 hours 9% vs 27%, P=0.049), and less sore throat (6% vs 48%, P<0.001). Late PONV decreased (3% vs 24%, P=0.013). There were no differences in pain scores and treatment.
CONCLUSION
In women who underwent breast surgery, IV lidocaine bolus administered just before extubation attenuated bucking, cough and sore throat, and PONV for 24 hours after general anesthesia, without prolonging the emergence.

OBJECTIVE
Intrathecal morphine is used as an effective component of multimodal analgesia in postoperative analgesia in cesarean section patients. We aimed to analyze the relationship between intrathecal morphine administration and postdural puncture headache (PDPH), pain score and analgesia consumption in the postoperative period, and maternal fetal effects.
METHODS
One hundred four pregnant women aged ≥18 years (American Society of Anesthesiology physical status I or II, >36 weeks gestation) who were scheduled for elective cesarean section under spinal anaesthesia were included in this study. Spinal anesthesia consisted of bupivacaine with or without morphine (Group M: 10 mg heavy marcaine + 25 mcg fentanyl + 100 mcg morphine; Group F: 10 mg heavy marcaine + 25 mcg fentanyl). The effect of intrathecal morphine on PDPH, postoperative pain score, analgesia consumption, and maternal and fetal effects were recorded for 5 days.
RESULTS
PDPH developed in a total of 33 patients (Group M: 18 and Group F: 15, =0.274). When we evaluated PDPH with the VAS, there was no significant difference between the groups. The postoperative visual analogue scale (VAS) was lower in the morphine group, and no statistically significant difference was found in the VAS 1 hr and VAS 2 hr, whereas the VAS 6 hr and VAS 24 hr were found to be statistically significant. There was no difference in terms of PDPH, the first analgesic requirement and postoperative nausea-vomiting, but meperidine consumption was lower in the morphine group.
CONCLUSION
Low-dose intrathecal morphine did not affect the incidence of PDPH. It is an effective method that can be used in cesarean section patients without increasing the maternal and fetal side effects from postoperative analgesia.

PURPOSE
Safe and effective analgesia sub partu is one of the central issues in optimizing vaginal delivery birth experiences. Meptazinol is a common opiate approved for treating labor pain in the first stage of labor. According to the manufacturer, manual meptazinol can be applied intramuscularly or intravenously. The aim of this study was to compare the two application methods in terms of efficacy in pain relief, occurrence of side effects and treatment satisfaction.
METHODS
132 patients with singleton term pregnancies and intended vaginal delivery, receiving meptazinol during first stage of labor were included in this prospective cohort study from 05/2020 to 01/2021. We evaluated effectiveness in pain relief and treatment satisfaction using numeric rating scales (NRS) and documented the occurrence of adverse effects. Chi-square test or Fisher exact test were used to compare categorical data and Mann-Whitney U test to compare continuous data between the two treatment groups. Statistical analysis was done by SPSS 27.0. A p value < 0.05 was considered to indicate statistical significance (two tailed).
RESULTS
Meptazinol decreased labor pain significantly from a NRS of 8 (IQR 8-10) to 6 (IQR 4.75-8) in both treatment groups with no difference in effectiveness between the groups. Frequency of effective pain reduction of a decrease of 2 or more on the NRS did not differ between groups (39.4% vs 54.5%, p = 0.116), as the occurrence of adverse effects. 12% of the newborns were admitted to NICU, the median NApH was 7.195.
CONCLUSION
Meptazinol significantly reduces labor pain regardless of the method of application: intramuscular or intravenous. According to our data, no preferable route could be identified. The comparably poorer perinatal outcome in our study cohort hinders us to confirm that meptazinol is safe and can be recommended without restrictions.
