Objectives The aim of this study was to evaluate the analgesic efficacy of oral tramadol in cats undergoing ovariohysterectomy. Methods Twenty-four female domestic cats, American Society of Anesthesiologists class I, aged 4–24 months, were included in this positive controlled, randomised, blinded clinical trial. Cats admitted for ovariohysterectomy were allocated to group oral tramadol (GOT, n = 12) or group intramuscular tramadol (GIMT, n = 12). In GOT, tramadol (6 mg/kg) was given orally 60 mins, and saline was given intramuscularly 30 mins, before induction of anaesthesia. In GIMT, granulated sugar in capsules was given orally 60 mins and tramadol (4 mg/kg) intramuscularly 30 mins before induction of anaesthesia. In both groups, dexmedetomidine (0.007 mg/kg) was given intramuscularly 30 mins before induction of anaesthesia with intravenous propofol. Anaesthesia was maintained with isoflurane in oxygen, and atipamezole (0.037 mg/kg) was given intramuscularly 10 mins after extubation. The UNESP-Botucatu multidimensional composite scale was used to conduct pain assessments before premedication and at 20, 60, 120, 240 and 360 mins post-extubation or until rescue analgesia was given. To compare groups, the 60 min postoperative pain scores and the highest postoperative pain scores were analysed via a two-tailed Mann–Whitney test, and the incidences of rescue analgesia were analysed via a Fisher’s exact test; P <0.05. Results There was no significant difference between groups for the 60 min ( P = 0.68) pain scores. The highest postoperative pain score was higher for GIMT compared with GOT ( P = 0.04). Only two cats required rescue analgesia, both from GIMT. The incidence of rescue analgesia was not significantly different between groups ( P = 0.46). Conclusions and relevance In the present study, preoperative administration of oral tramadol at 6 mg/kg to cats provided adequate analgesia for 6 h following ovariohysterectomy surgery.

Background and objective: Circumcision is one of the most common operations and can cause postoperative pain, fear, and anxiety for children. This study aims to compare the effects of transversus abdominis plane (TAP) block and caudal epidural (CE) anesthesia on postoperative analgesia after circumcision in providing postoperative pain control. Methods: Eighty boys aged 1 to 14 years who underwent elective circumcision surgery under general anesthesia either with USG-guided TAP block or with CE block for postoperative analgesia were enrolled consecutively to this prospective observational study equally in each group. Postoperative pain scores and need for rescue analgesia were recorded and compared between the two groups. Results: There was no statistically significant difference between the groups in mean age and Aldrete scores (p > 0.05). Body mass index (BMI) of the caudal block group was statistically lower than the TAP group (p < 0.05). While there was no statistically significant difference between the groups in 30th-minute VAS values (p > 0.05), the CE block group's 1st, 2nd, 4th, 8th, 12th, 18th, and 24th hour VAS values were statistically lower than the TAP block group's (p < 0.05). Conclusion: USG-guided TAB block under general anesthesia was not associated with lower postoperative pain scores and delayed rescue analgesia need compared with CE block in patients who underwent elective circumcision surgery. CE block provided superior analgesia than the USG-guided TAP block after elective circumcision surgery in this study.

Background: The physiological consequences of post-operative pain including Stress response to surgery, Respiratory complications, cardiovascular complications, Thromboembolic complications, Gastrointestinal complications, Musculoskeletal complications and Psychological complications, all of which could delay or impair postoperative recovery and increase the economic cost of surgery as a result of the longer period of hospitalization. Inadequate post-operative pain control may also lead to the development of chronic pain after surgery .Aim of This study: is to evaluate the preemptive analgesic effect of intravenous ketamine in laparoscopic cholecystectomy. Patients and Methods: double blinded randomized clinical trial conducted at Al-Yarmouk teaching hospital, over a period of one year from March 2013 to March 2014 on a total of 120 adult patients scheduled for elective laparoscopic cholecystectomy, Patients were divided in to three groups of 40 patients each, the study drug administered intravenously during induction. Groups A and B received ketamine in a dose of 1 and 0.5 mg/kg, respectively, whereas group C received isotonic saline. The degree of pain at rest and deep breathing postoperatively were estimated using VAS, time of first analgesic dose, total opioid consumption, nausea, vomiting and hallucination were recorded for 24 h postoperatively. Results: postoperative pain scores were significantly low in group A when compared with the other groups at most times in the first 24 hours. Highest pain score was in group C at 0 h. Postoperative analgesic consumption was minimum in group A then group B and highest in group C. There was little significant difference in the pain scores between groups B and C. Group A had a significantly higher blood MAP than group B at 0, 0.5 and 1 h. 7.5% incidence of hallucinations were in group A. Conclusion: According to this study we conclude that preemptive ketamine in a dose of 1 mg/kg has a definitive role in reducing postoperative pain and analgesic requirement in patients undergoing laparoscopic cholecystectomy. A low dose of 0.5 mg/kg had little significant in preemptive analgesic effect and in reducing analgesic requirement.

Objectives The aim of this study was to investigate the analgesic efficacy of methadone vs buprenorphine within the QUAD protocol for anaesthesia in cats undergoing ovariohysterectomy. Methods One hundred and twenty cats were recruited to an assessor-blinded, randomised clinical trial. Cats received either methadone (5  mg/m2) or buprenorphine (180 µg/m2) combined with ketamine, midazolam and medetomidine intramuscularly. Anaesthesia was maintained with isoflurane in oxygen. Atipamezole was administered at extubation. Pain was assessed using the feline Composite Measure Pain Scale (CMPS-F), a dynamic interactive visual analogue scale (DIVAS) and mechanical nociceptive threshold (MNT). Sedation, pain, heart rate and respiratory rate were measured prior to QUAD administration, before intubation, and 2, 4, 6 and 8 h post-QUAD administration. If indicated by the CMPS-F, rescue analgesia was provided with 0.5 mg/kg of methadone administered intramuscularly. Meloxicam was administered after the last assessment. Differences in pain scores between groups were compared using a two-way repeated-measures ANOVA and requirement for rescue analgesia was compared using a χ2 test. Results Cats administered methadone had lower CMPS-F scores over time ( P = 0.04). Eighteen of 60 cats required rescue analgesia in the methadone group vs 29/60 in the buprenorphine group ( P = 0.028). All cats that received rescue analgesia required it within 6 h post-QUAD administration. There were no differences between groups in MNT or pain measured using the DIVAS. Conclusions and relevance Methadone produced clinically superior postoperative analgesia for the first 8 h after neutering than buprenorphine when used within the QUAD protocol.

Background: Thoracotomy is one of the most painful surgeries, and failure to alleviate patients' pain can have dangerous consequences. Objectives: This study aimed to evaluate the addition of dexmedetomidine to ropivacaine in the intercostal block for postoperative pain control in patients undergoing thoracotomy. Methods: In this randomized clinical trial, 74 patients aged 18 to 60 years with ASA class I or II, BMI less than 40, and no severe systemic problems referred to a teaching hospital in Ahvaz to undergo thoracotomy were included in the study and randomly divided into two groups. After surgery, an ultrasound-guided intercostal block was done with ropivacaine (5 cc of 0.25% solution; group R) or ropivacaine (5 cc of 0.25% solution) plus dexmedetomidine (0.5 µg/kg; group RD) per dermatome. Two dermatomes above and two dermatomes below the level of surgical incision were used. Pain, total opioid consumption, length of ICU stays, time to first rescue analgesic, and time to get out of bed were compared between the two groups. Results: The intercostal block significantly reduced pain in both groups (P < 0.0001). The pain was lower in the RD group than in the R group from six hours after the intervention up to 24 hours after (P < 0.001). The number of patients who needed rescue analgesia at 12 hours was significantly lower in the RD group (P < 0.05). The RD group also had lower total opioid consumption and a longer time to receive the first rescue analgesia (P < 0.01). There was no significant difference between the two groups in the length of hospitalization and the time to get out of bed. Conclusions: Dexmedetomidine is an effective and safe choice to be used as an adjunct to ropivacaine in ICB, and it extends the duration of analgesia in combination with ropivacaine after thoracotomy.

Aim: In this study, it was aimed to investigate and compare the effects of menstrual cycle phases on preoperative anxiety and postoperative pain scores in patients given midazolam for premedication before anesthesia. Methods: Septorhinoplasty, goiter surgery and laparoscopic cholecystectomy 126 female patients, aged 21-45, with American Society of Anesthesiologists (ASA) score I-II and with regular menstrual cycles, were included. Of the cases; The phase of the menstrual cycle was recorded according to the last menstrual period (SAT) and accordingly the patients were divided into 3 groups as Follicular phase, the Ovulatory phase, and the Luteal phase. Anxiety assessment was performed using the State-Trait Anxiety Inventory (STAI FORM TX-1) test. Anxiety scores were evaluated by performing a preoperative test 3 minutes before and 1 hour after intravenous (IV) administration of 0.02 mg/kg midazolam. Visual analog scale (VAS) was used for postoperative pain assessment. Results: Midazolam was found to decrease STAI FORM TX-1 scores the most during the ovulatory phase of the menstrual cycle, but there was no significant difference between the groups in terms of VAS scores. Conclusion: It has been observed that premedication with midazolam reduces preoperative anxiety in all phases of the menstrual cycle in women of reproductive age, but is most effective in the ovulatory phase. The effect of premedication with midazolam on postoperative pain does not change according to the phases of the menstrual cycle.

The aim of this study was to evaluate laser acupuncture as an adjuvant for postoperative pain management in cats. Twenty cats, undergoing ovariohysterectomy, were sedated with intramuscular (IM) ketamine (5 mg kg−1), midazolam (0.5 mg kg−1), and tramadol (2 mg kg−1). Prior to induction of anaesthesia, the subjects were randomly distributed into two groups of 10 cats: Laser: bilateral stomach 36 and spleen 6 acupoints were stimulated with infrared laser; Control: no acupuncture was applied. Anaesthesia was induced using intravenous propofol (4 mg kg−1) and maintained with isoflurane. Postoperative analgesia was evaluated by a blinded assessor for 24 h following extubation using the Dynamic Interactive Visual Analogue Scale and Multidimensional Composite Pain Scale. Rescue analgesia was provided with IM tramadol (2 mg kg−1), and the pain scores were reassessed 30 min after the rescue intervention. If the analgesia remained insufficient, meloxicam (0.2 mg kg−1IM, single dose) was administered. Data were analyzed usingt-tests, the Mann-Whitney test, and the Friedman test (P<0.05). The pain scores did not differ between groups. However, postoperative supplemental analgesia was required by significantly more cats in the Control (5/10) compared with the Laser group (1/10) (P=0.038). Laser acupuncture reduced postoperative analgesic requirements in cats undergoing ovariohysterectomy.

Abstract Objectives Injection of a topical anaesthetic has been proved to be helpful with reducing pain after laparoscopic herniorrhaphy. We aimed to assess the effect of bupivacaine lavage on postoperative pain and compare it with diclofenac suppository. In this randomized clinical trial, 60 patients—scheduled for laparoscopic herniorrhaphy—were enrolled and randomized into three groups of 20 each, including diclofenac suppository, bupivacaine lavage, and normal saline as a placebo.The patients were investigated for postoperative pain scores, vomiting, nausea, morphine request, and duration of hospitalization. Results In the bupivacaine group, pain levels in recovery room, 4, 8 and 12 h after surgery, were significantly lower than diclofenac group; at time points of 16, 20 and 24 h after surgery, difference between two groups was not significant. Regarding vomiting and nausea, at time points of 1 and 3 h after surgery, results show no significant difference between the groups. Incident of infection, 1 h and 1 week after the surgery, was not significantly different among the groups. Duration of hospitalization in the bupivacaine group was much lower than the diclofenac group. Based on our results, use of the bupivacaine lavage can reduce postoperative pain in patients undergoing laparoscopic herniorrhaphy.

The concept of preemptive analgesia, albeit long-standing, has reemerged. Consequently, recent research has focused on testing a variety of drugs preoperatively to prevent the occurrence of postoperative pain, a major factor of morbidity. Amitriptyline is a tricyclic antidepressant used to treat chronic pain. Because amitriptyline acts on pain transmission pathways, it could theoretically be used as an agent for the prevention of postoperative pain. This study evaluated the effectiveness of amitriptyline in preventing pain in patients submitted to hysterectomy, the most commonly performed gynecological surgery. A randomized, double-blind clinical trial was conducted with 145 patients, 72 of these receiving amitriptyline and 73 placebo. All patients were evaluated at 6, 12, 24 and 48 hours after surgery using a visual analog scale (VAS) for pain and algometry to determine the pressure-pain threshold. Statistical analysis was conducted using the chi-square test of association, Student's t-test, and the Mann-Whitney test, with Fisher's exact test being used whenever appropriate. No statistically signicant difference was found between the two groups with respect to pain at any of the time points evaluated, leading to the conclusion that at a dose of 25 mg, amitriptyline is ineffective in preventing postoperative pain in patients submitted to abdominal hysterectomy

Abstract Background Well-controlled postoperative pain is essential for early recovery after uniportal video-assisted thoracoscopic surgery (UVATS). Conventional analgesia like opioids and thoracic epidural anaesthesia have been associated with hypotension and urinary retention. Intercostal catheters are a regional analgesic alternative that can be inserted during UVATS to avoid these adverse effects. This feasibility study aims to evaluate the postoperative pain scores and analgesic requirements with incorporation of an intercostal catheter into a multimodal analgesic strategy for UVATS. Methods In this observational study, 26 consecutive patients who underwent UVATS were administered a multilevel intercostal block and oral paracetamol. All of these patients received 0.2% ropivacaine continuously at 4 ml/h via an intercostal catheter at the level of the incision. Rescue analgesia including etoricoxib, gabapentin and opioids were prescribed using a pain ladder approach. Postoperative pain scores and analgesic usage were assessed. The secondary outcomes were postoperative complications, days to ambulation and length of stay. Results No technical difficulties were encountered during placement of the intercostal catheter. There was only one case of peri-catheter leakage. Mean pain score was 0.31 (range 0–2) on post-operative day 1 and was 0.00 by post-operative day 5. 16 patients (61.6%) required only oral rescue analgesia. The number of patients who required rescue non-opioids only increased from 1 in the first 7 months to 8 in the next 7 months. There were no cases of hypotension or urinary retention. Median time to ambulation was 1 day (range 1–2). Mean post-operative length of stay was 4.17 ± 2.50 days. Conclusions Incorporation of an intercostal catheter into a multimodal analgesia strategy for UVATS is feasible and may provide adequate pain control with decreased opioid usage.

Introduction: Pain control is an essential care for patients with renal colic in emergency wards. Objectives: This study aimed to compare the analgesic efficacy of intravenous (IV) paracetamol (PC) versus ketorolac (KET) for patients with renal colic. Patients and Methods: In a randomized controlled clinical trial, 110 patients with renal colic referred to the emergency department of Kosar hospital, Semnan between October 2015 and June 2016 were selected. Eighty-eight patients were divided into two groups (44 patients in each group) of PC (1 g/IV) and KET (30 mg/IV). One patient in each group was excluded during the study. Vital signs and pain severity (measured by visual analogue scale [VAS]) of all patients were recorded at admission time 0, 20, 40 and 60 minutes after treatment. Then, the results were compared in two groups. Results: The results showed that at the time of 0, 20, 40 and 60 minutes after the administration of the PC and KET drugs, no significant difference was seen in severity of pain based on VAS score between the two groups (P<0.05). Moreover, there were no significant differences in the vital signs of two groups (P<0.05). No adverse effects were reported in each group. Conclusion: In conclusion, the use of IV-PC and KET in patients with renal colic had similar pain relieving effects without any adverse effects.
