Background:Awake fiberoptic intubation (AFOI) is a recommended technique for anticipated difficult airway. An ideal regime should provide patient comfort, cooperation, amnesia, hemodynamic stability, and blunt airway reflexes and maintain a patent airway with spontaneous ventilation. The aim of our study was to compare intubation conditions between dexmedetomidine and fentanyl–midazolam combination during AFOI.Methods:This prospective, randomized study was conducted on a total of sixty patients of the American Society of Anesthesiologists physical status I and II of either sex, in the age group of 18–60 years having predicted difficult intubation undergoing elective surgeries and the patients were allocated to two groups of thirty patients each. After premedication and topicalization of airways, dexmedetomidine group (Group I, n = 30) received dexmedetomidine 1 μg/kg over 10 min and midazolam–fentanyl group (Group II, n = 30) received fentanyl 2 μg/kg plus midazolam 0.02 mg/kg over 10 min. Adequacy of intubation condition was evaluated by cough score and postintubation score. Incidence of desaturation, hemodynamic changes, and sedation using Ramsay sedation scale were noted and compared between two groups.Results:The demographic characteristics were comparable in the two groups (P > 0.05). The mean Ramsay sedation score in Group I was 3.13 ± 0.937 and Group II was 3.16 ± 0.949, and the comparison between two groups was statistically insignificant (P = 0.891). Cough scores and postintubation scores were favorable in dexmedetomidine group than midazolam–fentanyl group and were statistically significant with P < 0.001 and 0.0001, respectively. Group I also showed better hemodynamics and less episodes of desaturation than Group II.Conclusions:Dexmedetomidine is more effective than midazolam–fentanyl during AFOI, as it provides better intubation condition, hemodynamic stability, and preservation of airway and spontaneous ventilation.
OBJECTIVES : To study the role of dexmedetomidine on emergence agitation and its effect on extubation in paediatric adenotonsillectomy. Our study involves the assessment of postoperative pain by Objective Pain Scale and need for rescue analgesia and other untoward events in PACU. The study also included the comparision of post operative recovery time by Modified Aldrete Recovery Score using dexmedetomidine and normal saline in adenotonsillectomy for pediatric patients. METHODS : After induction of general anesthesia patient was put on controlled ventilation and maintained on sevoflurane 1.5-2% with 66% O2 and 33% N2O. At the end of surgery patients received either dexmedetomidine or normal saline over a period of 5 minutes, sevoflurane and nitrous oxide were discontinued, and residual muscle relaxation was reversed. Tracheal extubation time (time from anesthetic gas discontinue to tracheal extubation) and emergence time (time from anesthetic gas discontinue to eye opening on command) were recorded. Incidence of untoward airway events after extubation were also noted. The subject’s postoperative behaviour was assessed using Pediatric Anesthesia Emergence Delirium (PAED). In PACU, the intensity of pain was assessed by using an observational pain score (OPS). Any untoward events were noted and patient was shifted as per modified PACU score. RESULTS: In this randomized comparative study, single dose of dexmedetomidine (0.5mcg/kg) was found to be associated with a statistically significant decrease in the incidence of emergence agitation along with smooth extubation in pediatric patients undergoing adenotonsillectomy with sevoflurane anesthesia. In addition, lower incidence of post-operative nausea and vomiting, lower pain score and shorter duration of stay in post-anesthesia care unit were observed. Although it was seen that the extubation was prolonged in the dexmedetomidine group in comparison to the placebo. CONCLUSION: Dexmedetomidine reduces emergence agitation and provides smooth extubation in pediatric adenotonsillectomy patients on sevoflurane anesthesia.
Background: Spine surgeries particulary spine fusion surgeries provide a unique challenge with respect to postoperative analgesia as the choices to provide analgesia are limited. Uses of NSAIDS and neuroaxial anaesthesia for post-operative analgesia in spine surgeries have been controversial. Patient controlled analgesia with opioids is commonly used and morphine remains the gold standard. The aim of this study was to compare tramadol with morphine for postoperative analgesia in spine surgeries using iv patient controlled analgesia.Methods: A total of 80 adult patients of ASA grade I and 2 undergoing spine surgeries and divided into two groups i.e. morphine group M and tramadol group T with 40 patients in each group were included in the study. pain assessment was done by NRS (numeric rating scale) upto 48 hours postoperatively other parameters like nausea/vomiting and sedation were also noted. Both groups received boluses initially to control pain. Group M patients received 1mg i.v demand dose of morphine with lock out time of 10-15 minutes and in Group T patients PCA device was set to deliver 20mg i.v demand dose of tramadol with lock out time of 10-15 minutes. A bolus of 25mcg fentanyl was given as rescue analgesia in both groups by the nurse if required. No background infusion or four-hour maximal limit was set on PCA pumps.Results: Pain scores remained on lower side in both the groups, though slightly better with morphine and the difference was statistically significant at 4 hours, 12 hours and 24 hours. The total NRS mean value (0-48 hours) of morphine and tramadol is 3.270 and 3.629 with p value of 0.015 which is statistically significant. 7 patients in morphine group received rescue analgesia while it was received by 15 patients in tramadol group with p value of 0.78 which is statistically insignificant. Nausea and Vomiting was encountered more frequently in the tramadol group. Mean mobilization time in patients of tramadol group was 21.72 hours and that of morphine group was 17.10 hours with p value of 0.00 which is highly significant.Conclusions: Morphine and tramadol when used in PCA mode provide adequate pain relief post operatively after spine surgeries with morphine showing slightly better analgesia profile and significantly less nausea and vomiting than tramadol.
BACKGROUNDStudies have suggested a large inter-individual variation in postoperative pain after laparoscopic cholecystectomy, emphasising the need for improved analgesic treatment and valid predictors. Our study compared the effect of fentanyl plus intravenous paracetamol with fentanyl plus intravenous ketorolac for analgesic efficacy, opioid sparing effects and opioid-related side effects after laparoscopic cholecystectomy.
Introduction: Magnesium sulphate has the potential to treat and prevent pain by acting as an antagonist at N-methyl-DAspartate (NMDA) receptors. Many researchers found that magnesium sulphate as adjuvant to local anaesthetics reduces analgesic requirements in the postoperative period. Aim: To evaluate magnesium sulphate as an adjuvant to ropivacaine in ultrasound guided bilateral Transversus Abdominis Plane (TAP) block with respect to postlaparoscopic cholecystectomy pain. Materials and Methods: The present randomised doubleblind clinical study was conducted in the Department of Anaesthesiology, SKIMS Medical College, Srinagar, Jammu and Kashmir, between January 2022 and June 2022. Total 80 patients of American Society of Anesthesiologists (ASA) grade I and II were divided into two groups. Group A (n=40) patients received ropivacaine with magnesium and group B (n=40) patients received ropivacaine only. Pain was measured using the Visual Analogue Scale (VAS). Total rescue analgesia consumption during 24 hours, time to first request of rescue analgesia, postoperative nausea vomiting, sedation score and patient satisfaction score were recorded. Mann-Whitney U test was used for VAS score and patient satisfaction score. Results: Mean age of patients was higher in group A (47.95±13.853 years) than group B (46.45±11.940 years). Group A had 12 males and 28 females while in group B, there were 11 males and 29 females in group B. Group A showed better analgesic profile in the form of lower mean VAS, which were statistically significant (p-value<0.05). However, time to first request of rescue analgesia (743.5±58.214 minutes in group A vs 668.50± 214.375 minutes in group B; p-value=0.162) and total dose of rescue analgesia consumption were comparable in both groups (p-value>0.05). Also the sedation score (2.325±0.2529 in group A vs 2.295±0.2562 in group B; p-value=0.600) and patient satisfaction score (PSS) between the two groups (81.05±8.638 in group A vs 80.53±7.517 in group B; p-value=0.665) were statistically not significant. Incidence of postoperative nausea and vomiting was comparable in both groups (p-value=0.924). Conclusion: Addition of magnesium sulphate to ropivacaine in ultrasound guided bilateral TAP block significantly reduced pain scores in patients undergoing laparoscopic cholecystectomy.
BACKGROUNDThe introduction of safe drugs enhanced the popularity of spinal anaesthesia. Lofgren and Lundqvist introduced the most commonly used drug, Lignocaine. One of the disadvantages of Lignocaine was the association with transient neurological symptoms, which presents as low backache and lower extremity dysesthesia. Bupivacaine was introduced by Ekenstam in 1957. It is a well-established long-acting local anaesthetic used for spinal anaesthesia. It has been used frequently in spinal anaesthesia with a very little incidence of transient neurological symptoms. But it is associated with cardiovascular and central nervous system toxicity when used in high concentration or when accidentally administered intravascularly. Ropivacaine was introduced into clinical practice in 1996. It was initially used in epidural anaesthesia in lower extremity surgery, where it was compared with bupivacaine where they concluded that ropivacaine produced similar sensory and motor blockade with less cardiotoxicity. In a study, different concentrations of intrathecal ropivacaine 0.5% and 0.75% were compared for vascular surgery, which concluded that 15 mg of plain ropivacaine 0.75% is effective and safe and gives complete spinal anaesthesia in high risk patients without side effects and cardiovascular modifications.The aim of this study was to compare and evaluate the haemodynamic changes and side effects associated with equal volumes of two different doses of ropivacaine hydrochloride (0.75% and 0.5%) used in spinal anaesthesia in lower limb orthopaedic surgeries.
