Background: Wound infiltration with local anaesthetic is safe and effective technique for providing postoperative analgesia following lumbar laminectomy. The objective of this study was to compare the efficacy of local wound infiltration on postoperative analgesia with levobupivacaine, levobupivacaine plus magnesium sulphate and levobupivacaine plus dexmedetomidine in patient undergoing lumbar laminectomy.Methods: Ninety adult patients were randomly allocated into three groups. After the completion of lumbar laminectomy, the drug was locally infiltrated into the paravertebral muscles on either side. Group L received 10 ml of 0.5% levobupivacaine plus 10 ml normal saline, group LM received 10 ml of 0.5% levobupivacaine plus 500 mg magnesium sulphate (1 ml) plus 9 ml normal saline, group LD received 10 ml of 0.5% levobupivacaine plus 50 µg dexmedetomidine (0.5 ml) plus 9.5 ml normal saline. Postoperative visual analogue scale (VAS) pain score at 0, 1, 2, 4, 6, 8, 12 and 24 hours, time to first rescue analgesic drug and its total dose, quality of recovery score (QoR) and side effects were noted.Results: Postoperative VAS was significantly higher in group L as compared to group LM and LD (p<0.05). The time to first rescue analgesic drug was significantly longer in group LD (11.07±7.20 hr) than group LM (6.20±2.64 hr) and group L (3.93±2.70 hr) (p<0.001). The QoR score was significantly better in group LD as compared to group LM and L postoperatively (<0.01).Conclusions: Addition of magnesium sulphate or dexmedetomidine to levobupivacaine for local wound infiltration demonstrated enhanced postoperative analgesia.

AbstractBackground: Laminectomy is associated with considerable postoperative pain. Providing analgesia locally in the area of surgical trauma, with minimal systemic side effects, is an attractive option and has become an integral part of multimodal analgesia. The objective of this study was to assess and compare the effectiveness and safety of local infiltration of bupivacaine and bupivacaine plus magnesium sulphate for postoperative analgesia in patients undergoing lumbar laminectomy. Materials and Methods: Sixty adult patients of the American Society of Anaesthesiologists (ASA) class 1 and 2 were randomly allocated into two groups, comprising 30 patients in each group. After the completion of lumbar laminectomy, the study drug was locally infiltrated into the paravertebral muscles on either side. Group bupivacaine with magnesium (BM) was given 20 ml of 0.25% bupivacaine with 500 mg of magnesium sulphate (constituted with normal saline); and Group bupivacaine (B) was given 20 ml of 0.25% bupivacaine constituted with normal saline. Postoperative visual analogue scale (VAS) pain scores at 1, 2, 4, 6, 8, 12 and 24 hours; rescue analgesia, the time to first analgesic consumption, degree of overall patient satisfaction and side effects were recorded. Comparison of continuous data between groups was done using independent T-test. Comparison of nominal data was done using Chi-square analysis and ordinal data using Mann-Whitney test. A P value less than 0.05 was considered significant. Results: Time to first analgesic consumption was significantly longer in BM group (7.78 ± 1.350 hours) compared to B group (4.62 ± 0.997 hours) (P < 0.0001). The consumption of Tramadol was significantly higher in B group (202.5 ± 76.9 mg) compared to BM (117.5 ± 63.4 mg) (P < 0.0001). The degree of overall satisfaction with postoperative pain management on a 4-point satisfaction scale was better in BM group (2.77 ± 0.626) compared to B group (2.0 ± 0.587) (P < 0.001). Conclusion: Wound infiltration with bupivacaine and magnesium sulphate provided better pain control and analgesic effect was more significant, providing effective and safe postoperative analgesia in patients undergoing laminectomy surgeries.

Abstract Background Incidence of post dural puncture headache (PDPH) is relatively high, and many methods have been tried to prevent or treat it, but results are not satisfactory. Both Nalbuphine and Ketamine have analgesic effects, and have been used intrathecally with local anesthetics, but their effects on PDPH were not studied. Objective To study the incidence and severity of PDPH when nalbuphine or ketamine was added as an adjuvant to hyperbaric bupivacaine in spinal anesthesia (primary outcome). Secondary outcomes were the effects of adding nalbuphine or ketamine as an adjuvant to hyperbaric bupivacaine on motor and sensory effects, duration of analgesia, hemodynamics and side effects of both of them. Patients and Methods This prospective double-blind, randomized controlled study was conducted on 320 patients, aged 21–60 years of both sexes, ASA physical status I and II, and allocated for lower abdominal, pelvic, or lower limb surgeries under spinal anesthesia, after approval from ethical committee (Assurance No. FWA 000017585) of Faculty of Medicine, Ain, Shams University, Cairo, Egypt. Contact with 17 patients was lost. So, 303 patients completed the study. Patients were divided into 3 equal groups (101 each) according to drugs injected intrayhecally. Group (N): 3 ml of 0.5% hyperbaric bupivacaine with 0.5 mg nalbuphine hydrochloride diluted in 0.5 ml normal saline. Group (K): 3 ml of 0.5% hyperbaric bupivacaine with 25 mg ketamine hydrochloride diluted in 0.5 ml normal saline. Group (C): 3 ml of 0.5% hyperbaric bupivacaine with 0.5 ml normal saline. Results Incidence of PDPH was statistically significantly less in group N in comparison to Groups K and C, in the first day. But, no statistically significant difference was found between the three groups at 2nd and 3rd days. There was no statistically significant difference between groups according to severity of PDPH by visual analog score (VAS). Group N has the most rapid onset and long duration of sensory block in comparison with groups K and C. There was no statistically significant difference between groups according to onset and duration of motor block and hemodynamic changes. Conclusion Adding nalbuphine, and not ketamine, with hyperbaric bupivacaine in spinal anesthesia decreased incidence of post dural puncture headache, and prolonged the duration of sensory block. Both groups provided adequate anesthesia and analgesia with good hemodynamic stability.

Abstract Background: Hypothermia and shivering are associated common complications after spinal anesthesia especially in uroscopic procedures when large amounts of cold intraluminal irrigating fluids are used. Magnesium sulphate and dexmedetomidine are the most effective adjuvants with least side effects. Our aim of the study is to compare the effect of intrathecal dexmedetomidine versus intrathecal magnesium sulfate in prevention of post spinal shivering. Methods: This prospective randomized, double-blinded controlled study was conducted at Kasr El-Aini Hospital on 105 patients scheduled for uroscopic surgeries. patients were randomly allocated into three groups using computerized generated random tables, Group C (n=35) received 2.5 ml hyperbaric bupivacaine 0.5% (12.5 mg) +0.5 ml normal saline, Group M (n=35) received 2.5 ml hyperbaric bupivacaine 0.5% (12.5 mg) +25 mg magnesium sulfate in 0.5 ml saline and Group D (n=35) received 2.5 ml hyperbaric bupivacaine 0.5% (12.5mg) + 5 μg dexmedetomidine in 0.5 ml saline. Primary outcomes were the incidence and intensity of shivering. Secondary outcomes were incidence of hypothermia (Temp < 36° C), sedation, the use of meperidine to control shivering and complications, bradycardia, nausea and vomiting. Results: C group showed statistically significant higher number of total patients who developed shivering (21), patients who developed grade IV shivering (20) and patients who needed meperidine (21) to treat shivering than M group (8,5,5) and D group (5,3,6) which were comparable to each other. Time needed to give meperidine after giving the block was similar in the three groups. Hypothermia didn’t occur in any patient in the three groups. The three groups were comparable regarding occurrence of nausea, vomiting, bradycardia & hypotension. All patients of C group, 32 patients in M group and 33 patients in D group had sedation score of 2. 3 patients in M group and 2 patients in D group had a sedation score of 3. Conclusions: intrathecal injection of dexmedetomidine and magnesium sulfate were both effective in reducing the incidence of post spinal shivering. So, we encourage the use of magnesium sulphate being more physiological, readily available in most operating theatres and much cheaper than dexmedetomidine. Clinical trial registration ID: PACTR201801003001727, on January 2018.

Succinylcholine, a depolarizing muscle relaxant possesses a unique property of rapid onset and short duration of action, but is accompanied by side effects such as fasciculation and myalgia. The aim of this study was to investigate the prophylactic effect of intravenous lignocaine on the incidence and severity of succinylcholine-induced postoperative myalgia. This was a randomized controlled double blind study conducted at National Institute of ENT Dhaka, during September to December 2017. Eighty adult patients of American Society of Anesthesiologists status I and II of both sexes for elective surgery under general anesthesia were randomly allocated into two equal groups, lignocaine group and normal saline group. The patients of lignocaine group were pretreated with lignocaine 1.5 mg/kg body weight in 5 ml volume, while patients of normal saline group were given isotonic saline 0.9% in the same volume (5 ml) intravenously. Thereafter, anesthesia was induced in all patients, by injecting 1.5 mg/kg of fentanyl and 2 mg/kg of propofol intravenously. Following the loss of eyelid reflex, 1.5 mg/kg of succinylcholine was injected intravenously as a muscle relaxant and then the patients were intubated. The incidence and severity of myalgia were assessed by a blinded observer 24 hours after surgery. In terms of demographic data, the results of this study showed that there is no significant difference between patients in both groups (P>0.05). Overall, the incidence and severity of succinylcholine-induced myalgia in lignocaine group was significantly less, when compared with normal saline group (P<0.05). Pretreatment with intravenous lignocaine is effective in prevention of postoperative succinylcholine induced myalgia. Faridpur Med. Coll. J. Jan 2019;14(1): 13-15

Objective: To study the effectiveness of prophylactic ephedrine to prevent hypotension caused by induction of anesthesia with propofol and sufentanil in elderly hypertensive patients. Methodology: 70 elderly ASA grade II-III hypertensive patients undergoing elective general anesthesia were randomized into two groups to receive either intravenous ephedrine,100 ug/kg in 5ml normal saline (Group B), or an equal volume of normal saline (Group A) before induction. Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR) were recorded at T0 (after entry to the operating room), T1 (1 min after induction), T2 (2 min after induction), T3 ( 3 min after induction), T4 (4 min after induction), T5 (when intubated), T6 (2 min after intubation), and T7 (at the start of the procedure), as well as the incidence of hypotension and bradycardia. Results: SBP, DBP and HR were not significantly different at T0 and were significantly different at T1 to T7 after anesthesia induction. There were statistically significant effect on hypotension and bradycardia between the two groups and group B have a lower risk of hypotension and bradycardia relative to group A. SBP and DBP decreased significantly after induction in both groups. HR decreased significantly in group A while increased in group B. Conclusion: Ephedrine pretreatment can minimize hypotension and bradycardia caused by propofol and sufentanil during the induction of general anesthesia in elderly patients with hypertension.

Background: Nasal packing is commonly done after septal surgeries. Nonabsorbable nasal pack is used to minimize bleeding from surgery site, support the mucoperichondrial flaps, and minimize the risk of formation of septal hematomas and adhesions. However, these materials cause pain and discomfort in-situ as well as during removal. This study was done to evaluate the effect of 2% lignocaine rehydration of nasal pack on pain during pack removal. Methods: This prospective study was conducted on 60 patients who had undergone septoplasty. The patients were divided into 2 groups: Lignocaine and Normal saline group, with 30 patients each. In the Lignocaine group, 2.5 ml of 2% of lignocaine was diluted with 2.5 ml of distilled water and was injected into the nasal pack; and in Normal saline group, 5 ml of normal saline was injected into the nasal pack. Nothing was injected to the left nostril, which acted as a control, in both groups. All patients were asked severity of pain during removal of nasal packing by VAS. Results: In lignocaine group, mean pain score was 3.73 ± 1.63 on lignocaine side and 6.23 ± 1.69 on control side (U=109.5, p<0.001). In Normal saline group, it was 6.5 ± 1.7 on normal saline side and 6.23 ± 1.96 on control side (U=425.5, p=0.711). On comparing VAS between lignocaine and normal saline group, pain was significantly lower in the lignocaine group (U=112.5, p<0.001) Conclusion: Rehydrating nasal pack with 2% topical lignocaine is a useful method to reduce pain during nasal pack removal.

Background: Shivering is an undesirable complication following general anesthesia and spinal anesthesia, whose early control can reduce postoperative metabolic and respiratory complications. Therefore, this study aims to compare the effects of prophylactic injection of ketamine and pethidine on postoperative shivering. Methods: This double-blind clinical trial was performed on 105 patients with short-term orthopedic and ENT surgery. The patients were randomly divided into three groups; 20 minutes before the end of the surgery, 0.4 mg/kg of pethidine was injected to the first group, 0.5 mg/kg of ketamine was injected to the second group, and normal saline was injected to the third group. After the surgery, the tympanic membrane temperature was measured at 0, 10, 20, and 30 minutes. The shivering was also measured by a four-point grading from zero (no shivering) to four (severe shivering). Data were analyzed by one-way ANOVA, Kruskal Wallis, Chi-square and Pearson correlation. Results: The mean age of patients was 35.8+/-11.45 years in the ketamine group, 34.8+/-11.64 years in the normal saline group, and 33.11+/-10.5 years in the pethidine group. The one-way ANOVA showed no significant difference in the mean age between the three groups (P=0.645). The incidence and intensity of shivering were significantly higher in the normal saline group than in the ketamine and pethidine groups (p=0.001). However, there was no significant difference in the incidence and the intensity of shivering between the ketamine and the pethidine groups (p=0.936). Conclusion: The results showed that the 0.5 mg/kg of ketamine could control the post-anesthetic shivering.
