Background: In addition to chronic pain and anxiety disorders, few studies have found promising role of gabapentin in relieving acute postoperative pain as well as acute anxiety too. Objectives: To evaluate the effect of gabapentin premedication on preoperative anxiety and postoperative pain in patients undergoing elective open cholecystectomy. Methods: A prospective, randomized, double blind and placebo controlled study. Eighty adult patients of ASA I and II were divided into 2 groups of 40 each. Patients in group 1 and group 2 received capsules Gabapentin (1200mg) or identical placebo capsules 2 hours prior to surgery respectively. Preoperative anxiety and 12 hours postoperative pain was assessed using Anxiety and Pain VAS score respectively along with the observation of side effects. Postoperatively, intravenous pethidine 0.5 mg/kg was given when pain VAS > 40mm and time to first pethidine injection and total pethidine consumption in 12 hours was recorded. Results: Anxiety VAS scores after one hour of drug intake (35.75±20.11 versus 46.63±12.73) and just before induction of anaesthesia (45.75±30.27versus 68.13±29.84) along with postoperative Pain VAS scores were significantly lower in gabapentin group. Time to the first pethidine demand was significantly longer (145.34±194.54 min versus 26.30±51.02min) and cumulative pethidine consumption throughout study period was also significantly lower (35.91 ± 16.61 versus 57.84 ± 20.72mg) in gabapentin group. Conclusions: 1200 mg gabapentin premedication in open cholecystectomy patients significantly reduced preoperative anxiety, postoperative pain and total pethidine consumption with negligible side effects.

Chronic Anxiety

INTRODUCTION: The role of Gabapentin in relieving chronic pain, chronic anxiety disorders and acute postoperative pain is well known by now. Trials done with the administration of Gabapentin to treat preoperative anxiety showed mixed results. So, this study was conducted to test the hypothesis that premedication with Gabapentin 1200 mg versus placebo would reduce preoperative anxiety in patients undergoing open cholecystectomy under general anesthesia. MATERIAL AND METHODS: A prospective, randomized, double blind and placebo controlled study was carried out at Universal College of Medical Sciences & Teaching Hospital (UCMSTH) from August 2012 to Januray 2014. Total 160 adult patients of American Society of Anaesthesiologist (ASA) I and II were divided into 2 groups of 80 each. Patients in group 1 and group 2 received capsules Gabapentin (1200mg) or identical placebo capsules 2 hours prior to surgery respectively. Preoperative anxiety was assessed for three times using Anxiety Visual Analogue Scale (VAS) score. A uniform anesthetic technique was used in both groups. Parameters including preoperative and postoperative sedation scores and various side effects were also observed.RESULTS: VAS anxiety scores after one hour of drug intake (47.19±17.37 versus 63.13±17.77) and just before induction of anaesthesia (43.81±17.72 versus 81.81±21.57) were significantly lower in Gabapentin group as compared to placebo group. No patient experienced any significant side effects or sedation in either group throughout the study period.CONCLUSIONS: Premedication with 1200 mg Gabapentin in open cholecystectomy patients significantly reduced preoperative anxiety as evident by decrease in anxiety VAS scores without any significant side effects.  DOI: http://dx.doi.org/10.3126/jucms.v2i3.11821 Journal of Universal College of Medical Sciences Vol.2(3) 2014: 9-14

OBJECTIVE The aim of this study was to assess in-hospital (immediate) postoperative pain scores and analgesic consumption (primary goals) and preoperative anxiety and sleep quality (secondary goals) in patients who underwent craniotomy and were treated with pregabalin (PGL). Whenever possible, out-of-hospital pain scores and analgesics usage data were obtained as well. METHODS This prospective, randomized, double-blind and controlled study was conducted in consenting patients who underwent elective craniotomy for brain tumor resection at Tel Aviv Medical Center between 2012 and 2014. Patients received either 150 mg PGL (n = 50) or 500 mg starch (placebo; n = 50) on the evening before surgery, 1.5 hours before surgery, and twice daily for 72 hours following surgery. All patients spent the night before surgery in the hospital, and no other premedication was administered. Opioids and nonsteroidal antiinflammatory drugs were used for pain, which was self-rated by means of a numerical rating scale (score range 0–10). RESULTS Eighty-eight patients completed the study. Data on the American Society of Anesthesiologists class, age, body weight, duration of surgery, and intraoperative drugs were similar for both groups. The pain scores during postoperative Days 0 to 2 were significantly lower in the PGL group than in the placebo group (p < 0.01). Analgesic consumption was also lower in the PGL group, both immediately and 1 month after surgery. There were fewer requests for antiemetics in the PGL group, and the rate of postoperative nausea and vomiting was lower. The preoperative anxiety level and the quality of sleep were significantly better in the PGL group (p < 0.01). There were no PGL-associated major adverse events. CONCLUSIONS Perioperative use of twice-daily 150 mg pregabalin attenuates preoperative anxiety, improves sleep quality, and reduces postoperative pain scores and analgesic usage without increasing the rate of adverse effects.

Effective Pain Relief

A perioperative intravenous lidocaine infusion has been reported to decrease postoperative pain. The goal of this study was to evaluate the effectiveness of intravenous lidocaine in reducing postoperative pain for laparoscopic colectomy patients. Fifty-five patients scheduled for an elective laparoscopic colectomy were randomly assigned to 2 groups. Group L received an intravenous bolus injection of lidocaine 1.5 mg/kg before intubation, followed by 2 mg/kg/h continuous infusion during the operation. Group C received the same dosage of saline at the same time. Postoperative pain was assessed at 2, 4, 8, 12, 24, and 48 hours after surgery by using the visual analog scale (VAS). Fentanyl consumption by patient-controlled plus investigator-controlled rescue administration and the total number of button pushes were measured at 2, 4, 8, 12, 24, and 48 hours after surgery. In addition, C-reactive protein (CRP) levels were checked on the operation day and postoperative days 1, 2, 3, and 5. VAS scores were significantly lower in group L than group C until 24 hours after surgery. Fentanyl consumption was lower in group L than group C until 12 hours after surgery. Moreover, additional fentanyl injections and the total number of button pushes appeared to be lower in group L than group C (P &lt; 0.05). The CRP level tended to be lower in group L than group C, especially on postoperative day1 and 2 and appeared to be statistically significant. The satisfaction score was higher in group L than group C (P = 0.024). Intravenous lidocaine infusion during an operation reduces pain after a laparoscopic colectomy.

Abstract Background Patients undergoing bariatric surgery can have respiratory complications in addition to vomiting and ileus. Esmolol can decrease the consumption of opioids, reducing their side effects. The purpose of this study was to evaluate the analgesic effect of esmolol in patients allocated to laparoscopic gastroplasty. Methods Forty patients between 18 and 50 years old, of both genders, physical status ASA I-II, who underwent bypass gastroplasty were divided into two groups. Participants in group 1 received a 0.5 mg/kg bolus of esmolol in 30 mL of saline before induction of anesthesia, followed by infusion of 15µg/kg/min until the end of surgery; those in group 2 received 30 mL of saline bolus and infusion of solution in the same volume as group 1. The anesthesia included fentanyl (5ug/kg), propofol (2-4 mg/kg), rocuronium (0.6 mg/kg), 50% oxygen without nitrous oxide and 2% sevoflurane, with remifentanil if necessary. There were evaluated: remifentanil consumption, time to analgesic supplementation, pain intensity for 24 h and morphine dose over 24 h. Side effects were noted. Results Intraoperative remifentanil supplementation, time to recovery, and postoperative morphine supplementation were lower in the esmolol group; there was no difference in time for the first supplementation. Pain intensity was lower, except at T0 and after 12 h. There were no differences in side effects. Conclusions Intraoperative esmolol promotes an analgesic effect without causing adverse effects, making it an effective drug for multimodal analgesia for gastroplasty.

Abstract Background Pregabalin is a gabapentinoid which has been shown to possess analgesic and anxiolytic properties. The present study aimed to assess the efficacy of a single dose of pregabalin on postoperative pain and preoperative anxiety in patients undergoing lumbar spine surgery. Materials and Methods Sixty adults posted for elective lumbar laminectomy and discectomy were randomly assigned to one of the three groups; Group C received placebo capsules, Group PI received pregabalin 150 mg, and Group P2 received pregabalin 300 mg capsules, 2 h prior to induction of anesthesia. The levels of anxiety and pain were assessed with respective 100 mm visual analog scale (VAS) score. Postoperative fentanyl consumption and occurrence of side effects were recorded. All patients were observed for 8 h, postoperatively. Results There was a significant reduction in preoperative anxiety in both pregabalin groups as compared to control group (p = 0.001). VAS score for pain (at rest and during movement) was significantly decreased at all time intervals in both PI and P2 groups as compared to control (p < 0.05). Fentanyl consumption in the postoperative period was significantly reduced in pregabalin groups as compared to control (p = 0.001). The level of sedation was higher in P2 group in the first 4 h (p < 0.05). The occurrence of postoperative nausea and vomiting was more in control group as compared to the pregabalin groups (p = 0.018). The incidence of dizziness and blurring of vision was significantly more in P2 group. Conclusion Single preoperative dose of pregabalin 150 or 300 mg was effective in reducing preoperative anxiety, postoperative pain and total fentanyl consumption in patients undergoing lumbar laminectomy and discectomy. However, the incidence of postoperative side effects such as sedation, dizziness and visual blurring was more in patients who received pregabalin 300 mg.

Pain At Rest

Background The anticonvulsant gabapentin has proven effective for neuropathic pain in three large placebo-controlled clinical trials. Experimental and clinical studies have demonstrated antihyperalgesic effects in models involving central neuronal sensitization. It has been suggested that central neuronal sensitization may play an important role in postoperative pain. The aim of the study was to investigate the effect of gabapentin on morphine consumption and postoperative pain in patients undergoing radical mastectomy. Methods In a randomized, double-blind, placebo-controlled study, 70 patients received a single dose of oral gabapentin (1,200 mg) or placebo 1 h before surgery. Patients received patient-controlled analgesia with morphine at doses of 2.5 mg with a lock-out time of 10 min for 4 h postoperatively. Pain was assessed on a visual analog scale at rest and during movement, and side effects were assessed on a four-point verbal scale 2 and 4 h postoperatively. Results Thirty-one patients in the gabapentin group and 34 patients in the placebo group completed the study. Gabapentin reduced total morphine consumption from a median of 29 (interquartile range, 21-33) to 15 (10-19) mg (P&lt; 0.0001). Pain during movement was reduced from 41 (31-59) to 22 (10-38) mm at 2 h postoperatively (P &lt; 0.0001) and from 31 (12-40) to 9 (3-34) mm at 4 h postoperatively (P = 0.018). No significant differences between groups were observed with regard to pain at rest or side effects. Conclusion A single dose of 1,200 mg oral gabapentin resulted in a substantial reduction in postoperative morphine consumption and movement-related pain after radical mastectomy, without significant side effects. These promising results should be validated in other acute pain models involving central neuronal sensitization.

Background: The proper management of postoperative pain improves patients’ quality of life, accelerates early postoperative recovery, shortens hospitalization period, and reduces medical costs. This study aimed to compare the effectiveness of intravenous fentanyl pump and sublingual buprenorphine tablet in controlling pain after open cholecystectomy. Objectives: Evaluating the effectiveness of sublingual buprenorphine in reducing postoperative pain and complications after open cholecystectomy. Methods: This study was a double-blind, randomized clinical trial. The study population encompassed those candidates undergoing open cholecystectomy, patients with ASA class I and II, individuals undergoing no other concomitant surgery, and patients in the age range of 20 - 50 years. The first group received sublingual buprenorphine 6, 12, and 18 hours after the first administration. The second group received fentanyl as patient-controlled analgesia (PCA) for 24 hours. Then nausea, vomiting, sedation, and Visual Analog Scale (VAS) scores were evaluated at the beginning, 2, 6, 12, 18, and 24 hours after surgery. The collected data were analyzed using SPSS software version 20. Results: The mean age of the patients in the buprenorphine and fentanyl groups were 44.8 ± 5.5 and 42.8 ± 7.1 years, respectively. In this study, 22.5% of the patients in the buprenorphine group and 35.5% of the patients in the fentanyl group were male. During 6 and 24 hours after surgery, the pain level regarding the VAS scores was significantly lower in the buprenorphine group than in the fentanyl group; however, analgesic consumption was higher in the fentanyl group. In the early hours after surgery (2 and 6 hours), nausea and vomiting were lower in the buprenorphine group than in the fentanyl group even though the difference was not significant. Conclusions: This study suggests buprenorphine as an effective drug for patients to reduce postoperative pain because of its limited complications, inexpensiveness, and more convenient administration method.

This prospective clinical study was carried out in the Dept. of Anaesthesia, Analgesia and Intensive Care Medicine, BSMMU, Dhaka, during the period of May 2003 to July 2003. The study was done to emphasize the importance of giving analgesics preemptively instead of waiting for the child to complain of pain and to produce smooth recovery after surgery by decreasing immediate postoperative pain in children by a simple, safe acceptable drug. The children scheduled for tonsillectomy under general anaesthesia were recruited in this study. The analgesic efficiency of rectal paracetamol in two doses, 25 mg/kg bodywt.(Gr-P25) and 50 mg/kg. bodywt. (Gr-P50) were compared with Diclofenac Sodium suppository 1mg/ kg body weight (Gr-D) given half an hour before induction of anaesthesia. Pain scoring was done by TPPPS (Toddler Pre-schooler postoperative pain scale). Heart rate and blood pressure were stable in Gr-P50 and Gr-D. Time of first demand of analgesic was delayed in Gr-P50 and Gr-D. Total paracetamol consumption in 24 hours was less in Gr-P50(181±14.25) and Gr-D (212±25) than Gr-P25(318± 26.39). Total duration of analgesia in Gr- P50 (657±9.94) mins. and in Gr- D(502±10.63) mins. and in Gr-P25(288±23.17) mins. Pre-emptive high dose rectal paracetamol appears to be more effective than diclofenac sodium suppository for postoperative analgesia in children undergoing tonsillectomy.

Induction Of Anaesthesia

The present study was done to evaluate the ability of oral pregabalin to attenuate the pressor response to airway instrumentation in patients undergoing laparoscopic cholecystectomy under general anesthesia. Sixty-four adult patients aged between 25-55 year of either gender belonging to ASA-1 or ASA2 physical status weighing 50-70 kg were enrolled in this study. Thirty-two patients each were randomized to group A, or group B. Patients in group A received tablet Pregabalin (150mg) and those in group B received placebo orally one hour before induction of anaesthesia. Heart rate, blood pressure, and sedation were assessed preoperatively before giving the tablets and after 30 minutes, and just before induction of anaesthesia. Intraoperative, pulse rate, mean arterial pressure, ECG in the lead II, SPO2 and ETCO2 were monitored. All the above parameters were noted during laryngoscopy and intubation, 3 minutes after CO2 insufflation, and then at every 10-minute interval till the end of surgery. These parameters were also recorded after extubating the patient. The Ramsay sedation scale was used to assess the sedation at the baseline, one hour after drug intake , one hour after extubation and 4 hour after surgery. Any adverse effects in the postoperative period were recorded. The result of our study shows that pre-emptive administration of oral pregabalin 150 mg significantly reduced the pressor response at the time of laryngoscopy and intubation, after CO2 insufflation and just after extubation. We conclude that oral pregabalin premedication is effective in successful attenuation of hemodynamic pressor response to laryngoscopy, intubation and pneumoperitoneum in patients undergoing laparoscopic cholecystectomy
