Comparative study of epidural clonidine versus dexmedetomidine as an adjuvant to bupivacaine for post-operative analgesia in infra umbilical surgeries under combined spinal epidural anaesthesia
Journal Title: Medpulse International Journal of Anesthesiology - Year 2019, Vol 9, Issue 3
Abstract
Background: Postoperative pain is an acute pain which starts with surgical trauma and ends with tissue healing. Clonidine is an alpha-2 receptor agonist. Dexmedetomidine is an super selective alpha–2 agonist made up of medetomidine’s dextrogyrous enatiomer. They produces analgesia with haemodynamic changes and minimum side effects. Methods: A clinical study of 70 cases of ASA grade 1 and2 between the age group 25-65yrs undergoing abdominal, obstetrical, gynaecological and orthopaedic surgeries under epidural anaesthesia. At the end of surgery patients were allocated to receive either of (Group – C) Clonidine 2 g /kg with 5 ml of Normal saline. (No = 35) or (Group – D) Dexmeditomidine 1g /kg with 5 ml of Normal saline. (No = 35). Cardio-respiratory effects like Pulse rate, blood pressure, respiratory rate and side effects like nausea, vomiting, pruritus, hypotension, sedation, respiratory depress ion were studied. Continuous data was analyzed by student's “t”-test and categorical data by Chi-square test and possible significance has been determined considering it statistically significant if the P value < 0.05. Results: The duration of analgesia in group -D (440.57 + 45.89 (SD) min)was significantly more when compared to group -C (325.71+ 48.89 (SD) min).In comparison of Group C and Group D, by using the unpaired student t test, highly significant difference in VAS was seen from 2.5 hours till 6hrs in between the groups. In addition Group D patients did not experience pain till 7th and 8th hour but Group C patients experienced pain at the end of 6 hours itself. Highly significant difference in sedation score was seen from 0 min till 6hrs in between the groups. In addition sedation was prolonged in Group D patients till 7th to 8th hours, but in Group C the sedation was persisting up to 4 hours. Conclusion: It was concluded that epidural dexmedetomidine provides an excellent and prolonged duration of analgesia when compared to epidural clonidine. Longer duration of analgesia along with good sedation was also seen when compared with clonidine group

The efficacy of two different doses of gabapentin (300mg and 600mg) along with NSAID (diclofenac transdermal patch 100mg) in postoperative pain management following abdominal hysterectomy
Context: Gabapentin, an antiepileptic drug has a role in acute postoperative pain management due to its anti hyperalgesic property. Pre-emptive analgesia is the recent concept in multi modal pain management. The purpose...
Effect of carbon dioxide pneumoperitoneum on acid base balance during laparoscopic surgeries
Background: Carbon dioxide is the most commonly used gas to induce pneumoperitoneum during laparoscopic surgeries, as CO2 levels in blood and expiratory gas can be easily measured and monitored. However, insufflations of...
A comparative study of 0.5% bupivacaine and 0.5% levobupivacaine in supraclavicular block in a tertiary care hospital
Background: supraclavicular brachial plexus block have assumed important role in modern anaesthesia practice as they provide ideal effective conditions without any general anaesthesia or adverse haemodynamic effects. Whi...
Dexmedetomidine versus Esmolol to attenuate the extubation response following surgeries under general anaesthesia - A comparative study
Background: Extubation of trachea always brings about acute, transient, undesirable hemodynamic and airway response which is sometimes fatal in susceptible patients. To attenuate this undesirable extubation response Dexm...
Comparison of intrathecal clonidine and dexmedetomidine as adjuvant to bupivacaine for hemodynamic response and postoperative analgesia in infraumbilical surgeries
Background: Clonidine and Dexmedetomidine is commonly used adjuncts with hyperbaric Bupivacaine in spinal anaesthesia. Both are α2 adrenergic agoinsts. Dexmedetomidine is comparatively newer drug with lesser side effects...
