Introduction: Spinal anesthesia is the preferred means for gynecological surgeries. Adjuvants to local anesthesia for spinal anesthesia may enhance quality and duration of analgesia. Our study aimed to evaluate efficacy and safety of fentanyl added to bupivacaine for spinal anesthesia. Methods: A prospective, randomized, double blind study was conducted on 60 ASA I or II adult female patients undergoing vaginal hysterectomy under spinal anesthesia. Patients were randomly divided into two groups. Patients in Group B (n=30) were administered 3 mL of 0.5% hyperbaric bupivacaine with 0.4 ml NS and Group F (n=30) were given 3 mL of 0.5% hyperbaric bupivacaine with 0.4 ml (20μg) fentanyl intrathecally. Hemodynamic variables (i.e. heart rate, noninvasive blood pressure, oxygen saturation), onset of motor and sensory block, duration of sensory and motor blockade and any side effects observed were recorded intraoperatively and postoperatively. Results: The duration of sensory and motor blockade was significantly prolonged (P<0.05) in fentanyl group (268.6±55.4 and 182.8±43.87) compared to control group (235.03±51.97 and 149.47±38.75). Similarly, the onset of sensory and motor block was significantly earlier (P<0.05) in group F (5.2±2.55 and 7.8±2.91) compared to group B (6.63±2.88 and 9.97±3.28). There was no significant statistical difference in the incidence of side effects and changes in hemodynamic variables in both the groups. No adverse events were observed during study. Conclusion: Addition of fentanyl to hyperbaric bupivacaine for spinal anesthesia offers early onset, better surgical analgesia, prolongs the duration of analgesia without any significant adverse effects.

ABSTRACTObjectives: Intrathecal fentanyl and clonidine are effective analgesics with different mechanisms of action. This study compares 25 µg of both thesedrugs given intrathecally regarding onset, quality, and duration of hyperbaric bupivacaine-induced spinal block and side effects.Methods: A total of 90 patients of ASA I and II were randomly allocated into three equal groups. Group A received 0.5 ml of 0.9% normal saline(placebo), Group B and Group C received 25 µg fentanyl and clonidine intrathecally added to 2.5 ml of 0.5% hyperbaric bupivacaine, respectively. Theonset and regression time of sensory and motor blocks were recorded along with hemodynamic change, side effects, pain intensity (in terms of visualanalog score (VAS), and time to first rescue analgesic.Results: Intrathecal clonidine (25 μg) significantly prolongs sensory and motor blocks, with prolonged duration of analgesia in comparison withintrathecal fentanyl (25 µg) (325±15 minutes vs. 240±7.6 minutes). VAS score was similar, but sedation was more in clonidine group.Conclusion: We conclude that low-dose intrathecal clonidine is an effective adjuvant to bupivacaine for spinal anesthesia and provides betterpostoperative analgesia in comparison with intrathecal fentanyl.Keywords: Clonidine, Fentanyl, Bupivacaine, Regional, Spinal, Postoperative pain.

PURPOSE To determine the most effective dose of leucovorin (folinic acid [FA]) within a weekly bolus fluorouracil (FU) schedule, we conducted a randomized multicenter trial to compare therapeutic effects and toxicity of high-dose FA versus low-dose FA combined with FU at equal doses in both treatment groups. PATIENTS AND METHODS Patients with measurable inoperable or metastatic colorectal cancer were randomized to receive weekly FU 500 mg/m2 by intravenous (IV) bolus combined with high-dose FA 500 mg/m2 (group A) or low-dose FA 20 mg/m2 (group B) by 2-hour infusion. RESULTS Of 291 assessable patients (group A, n = 148; group B, n = 143), we observed, in group A, complete response (CR)/partial response (PR) in 32 (21.6%), no change (NC) in 64 (43.2%), and progressive disease (PD) in 52 (35.1%); and in group B, CR/PR in 25 (17.5%), NC in 63 (44.1%), and PD in 55 (38.5%). The median response duration was 24.8 weeks in group A and 23.1 weeks in group B. Median progression-free intervals were 29.3 weeks (group A) and 30 weeks (group B). The median survival time was 55.1 weeks in group A and 54.1 weeks in group B. Overall toxicity was moderate. Mild nausea and vomiting, and stomatitis were common side effects in both groups. The incidence of World Health Organization (WHO) grade III/IV diarrhea was significantly higher in group A (40 v 23 patients). Severe side effects were observed only in a minority of patients in both arms. WHO grade IV diarrhea was observed in seven patients: four in group A and three in group B. The rate of toxicity-related adjustments of dose and schedule was comparable in both groups. CONCLUSION High-dose FA/FU is not superior to low-dose FA/FU within a weekly treatment schedule. Response rates and survival were comparable in both treatment arms. Treatment-related toxicity was higher in group A (high-dose FA). Therefore, low-dose FA combined with weekly FU may be considered the preferred treatment for metastatic colorectal cancer.

Background: We assessed whether intrathecal low-dose bupivacaine with dexmedetomidine could reduce the incidence of spinal anesthesia (SA)-related hypotension. Methods: In total, 47 patients undergoing urological or orthopedic surgery under SA were randomized into two groups. SA was induced using 12.5 mg of hyperbaric bupivacaine alone (Group B; n = 24 patients) or 6 mg of hyperbaric bupivacaine plus 4 μg of dexmedetomidine and 0.3 ml of saline (Group BD; n = 23 patients). At 10 min after SA, dexmedetomidine was infused in both groups at a loading dose of 0.5 µg/kg, administered over 10 min, and then maintained at a dose of 0.2 µg/kg/h for 40 min. Results: The incidence of hypotension was significantly higher in Group B than in Group BD (50.0 vs. 17.4%, P = 0.018). The amount of ephedrine used to treat hypotension was significantly higher in Group B than in Group BD (median [range], 3 [0–30] vs. 0 [0–12] mg, P = 0.014). Conclusion: Low-dose bupivacaine plus dexmedetomidine SA reduced the incidence of hypotension compared to conventional bupivacaine SA.

Background: Oral isotretinoin is the recommended treatment for acne vulgaris, a skin disease especially common in teenagers and adolescents. This study was designed to compare the efficacy and safety of low dose with high dose isotretinoin in severe acne vulgaris patients.Material and Methods: This randomized controlled trial included 110 patients with a clinical diagnosis of acne vulgaris. They were divided into two groups. Both groups were matched for age (mean 18.2±3.7 vs 17.6±3.2 years), weight (mean 58±10.2 vs 60.7±9.3 Kg), gender and disease duration (3±1.1 vs 3±1.0 years). Group A received low dose oral isotretinoin (20 mg/day) while group B received standard high dose regimen (1mg/kg/day). All patients were followed up for 16 weeks to assess efficacy (assessment of complete remission) and safety (mucocutaneous side effects). All calculations were performed using SPSS v. 16 with p value <0.05 considered as statistically significant.Results: There was no statistically significant difference in efficacy. However, significantly fewer mucocutaneous side effects were reported in group A (80%) as compared to group B (100%). This safety profile spectrum was observed across all pre-defined subsets i.e chielitis (78.1% vs 98.2%), dry skin (69.1% vs 92.7%), dry mouth (47.2% vs 72.7%) and facial rash (12.7% vs 30.9%).Conclusion: In patients with severe acne vulgaris, efficacy (complete remission) of low dose oral isotretinoin is almost equal to conventional high dose regimen but it is statistically superior in terms of safety (mucocutaneous side effects).

Objective: The purpose of the study is to compare and assess the sensoryand motor block along with the associated hemodynamic changes that occur in the patientpopulation operated for a lower segment cesarean section (LSCS), when they are given 0.5%hyperbaric bupivacaine versus 0.5% isobaric bupivacaine as used for spinal anesthesia.Study Design: Prospective double blind randomized trial. Period: 6 months duration fromApril 2014 to September 2014. Setting: A tertiary care hospital in the city of Karachi, Pakistan.Method: The study population consisted of 60 patients belonging to the ASA 1 and ASA 2category, who underwent a lower segment cesarean section, and comparative analysis ofthe efficacy and associated hemodynamic changes of hyperbaric with isobaric bupivacaine.The patient population was segmented into two groups both groups containing 30 patients,group A receiving hyperbaric bupivacaine 0.5% as 2.5ml ( 12.5mg dose ) and the secondgroup designated as, group B receiving isobaric bupivacaine 0.5% as 2.5ml ( 12.5mg dose)intrathecally. The resultant sensory and motor blockade was determined using pin prick andbromage scale respectively. Results: There was a significant difference found among the twogroups under study, when compared at 3min interval regarding the sensory blockade. The levelof T6 block was reached in 33.33% (n=10) patients belonging to group A and 56.66% (n= 17)patients in group B. It was observed that there was no significant change among the two groupsat 5min interval regarding sensory and motor blockade respectively. The immediate sensoryblockade with isobaric bupivacaine in group B produced greater decrease in the systolic andmean arterial blood pressure when contrasted with hyperbaric bupivacaine in group A at 5mininterval, but after time interval of 45min there was no statistically significant change observed.Conclusions: According to our study the effects of isobaric bupivacaine were more significantlypredictable; hence have a higher efficacy, when contrasted against hyperbaric bupivacainein lower section cesarean section spinal anesthesia. Quick sensory blockade with isobaricbupivacaine was associated with more decrease in blood pressures when contrasted with thehyperbaric bupivacaine, but this result is not statistically significant.

Background: Spinal anaesthesia remains one of the basic techniques in the arsenal of modern anaesthesiology despite the waxing and waning of its popularity over last 100 years since its introduction into clinical practice.It avoids biochemical and metabolic changes consequent to the stress of general anesthesia for surgery as well as provides near optimal conditions for surgery. In present study, we tried to study effectiveness of intrathecal 0.5% heavy bupivacaine alone with Dexmedetomidine as an adjuvant to intrathecal 0.5% heavy bupivacaine for lower limb and lower abdominal surgeries.Methods: The present study was conducted in the department of anaesthesiology from December 2011 to September 2013.This study was a prospective, randomised controlled, single blind, study conducted in 100 patients of ASA grade I and II undergoing elective surgeries under spinal anaesthesia. The patients were divided randomly into two groups, containing 50 patients in each group. Dosages of drugs selected are divided as Group B: Patients received 3 ml of 0.5% hyperbaric bupivacaine (15mg) and Group BD: Patients received 3 ml of 0.5% hyperbaric bupivacaine (15mg) plus 10 µg Dexmedetomidine. Spinal block characteristics, Mean arterial pressure, Mean pulse rate, sedation and side effects were studied during intra-operative and postoperative period.Results: It was found from present study that in Dexmedetomidine group time to reach T10 sensory blockade and complete motor blockade was earlier and a higher level of sensory blockade compared to control group achieved. Duration of sensory, motor blockade and duration of analgesia was significantly prolonged in the Dexmedetomidine group compared to the control group. Hemodynamic parameters were preserved both intra-operatively and postoperatively. However there were a small percentage of patients who developed hypotension and bradycardia which were easily managed without any untoward effect. Hence Dexmedetomidine is a better neuraxial adjuvant for providing early onset of sensory and motor blockade, prolonged sensory blockade and post operative analgesia and adequate sedation.Conclusions: Intrathecal low dose Dexmedetomidine in a dose of 10µg along with 0.5% hyperbaric bupivacaine is an addition into anaesthesiologist's armamentarium for spinal anaesthesia in patients undergoing elective lower abdominal and lower limb surgeries.
