123TEG measurement and second sample for laboratory tests. The following TEG data were obtained-reaction time, kinetic time, alpha angle, and maximum amplitude (MA). The following laboratory tests were obtained-haematology (haemoglobin, TLC, DLC, platelet count) and coagulation test [prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT)]. Result Out of 100 patients enrolled in the study, 80 (80 %) had a normal coagulation profile, while remaining 20 (20 %) had hypocoagulation profile. The results show that TEG parameters have a good correlation with conventional coagulation profile and also showed excellent independent predictive efficacy for prediction of hypocoagulation. PT, aPTT, and TT were directly proportional to R-time and K-time and inversely proportional to alpha angle (p \ 0.001). Platelet count showed a strong positive correlation with MA (p \ 0.001). Conclusion By giving a global picture of haemostasis, TEG can lead to improved decision-making about safety of using regional anaesthesia. Its fast feedback time makes it ideal for monitoring in a fast moving situation such as in obstetric emergency.
Background: Feeling of pain is one of the most important emotional determinants which dominate the perception of females who undergo the process of labour and delivery. Patient controlled epidural labour analgesia (PCEA) is convenient and safer technique for this purpose. Very few studies compared clonidine and fentanyl with ropivacaine in labour analgesia in past. This study was undertaken to compare fentanyl and clonidine in PCEA. Aims:To compare low concentration ropivacaine with or without fentanyl or clonidine for labour analgesia and its effect on maternal and foetal safety. Settings and Design:Prospective, double blind, randomized, comparative study. Materials and Methods:Ninety primegravida in labour were divided into three groups (n=30) and patient controlled epidural labour analgesia was given to them: Initial bolus of 10ml of ropivacaine 0.125% in Group I; with fentanyl 2 µg/ml in Group II and with clonidine 1µg/kg in Group III. Subsequently each group received ropivacaine 0.125% through patient controlled epidural analgesia (PCEA) as background infusion of 5 ml/hr with lockout interval time of 10min and subsequent bolus of 5ml. Hemodynamic parameters, sensory level, motor block and pain relief were noted. Total analgesic dose of local anaesthetic and feto-maternal adverse effects were also recorded.Results: At baseline, groups were matched demographically, hemodynamically as well as for intensity of pain. There was a statistically significant decrease in hemodynamic parameters from baseline in all groups with maximum reduction in group III. A significant difference among groups in VAS was observed at zero min and from 120min till 240min intervals and lowest values were in Group III. No significant difference was observed among the groups for mode of delivery and expulsive efforts. Total analgesic dose and PCA bolus requirement was maximum in Group I and minimum in Group III and the difference was statistically significant among groups. Six (20%) patients had shivering in Group II and hypotension was recorded in only 1 (3.3%) patient of Group III.Conclusion: Ropivacaine 0.125% was effective in decreasing labour pain without any motor blockade. Clonidine 1µg/kg was superior to fentanyl 2µg/ml as an
We are presenting a case report of 2 yrs. old male child with large sublingual ranula causing difficulty in airway management during general anaesthesia. We intubated the child after induction with sevoflurane, preserving spontaneous respiration. Muscle relaxant was not used for laryngoscopy and intubation.
BackgroundThe epidural analgesia technique is effective for labor analgesia and combinations of various local anesthetics with lipophilic opioids like fentanyl are used. However, fentanyl can cause an increased incidence of pruritus, urinary retention, nausea, vomiting, giddiness, shivering, and respiratory depression. Dexmedetomidine and clonidine are selective alpha 2 agonists with analgesic properties and have been used via the neuraxial route with local anesthetics for the same without the side effects of fentanyl. Thus, the primary objective was to assess and compare the analgesic efficacy of the two-drug combinations by the visual analog scale (VAS) score. MethodsFifty-four primigravida women were randomly allocated in two groups of 27 each and were given an initial bolus of 10 mL of 0.125% levobupivacaine with dexmedetomidine 0.5 ug/kg in Group A and with clonidine 1 μg/kg in Group B. Subsequently, each patient received a background infusion rate of 10 mL/h, a bolus dose of 5 ml, and a lock-out interval of 10 min via a patient-controlled-analgesia (PCA) pump. The blood pressure, heart rate, and severity of pain using VAS were assessed. Durations of the stages of labor, rate of instrumental delivery, and cesarean section, side effects, maternal sedation, and neonatal Apgar scores were also recorded. ResultsVAS scores in both the groups progressively decreased to <3 by 15 min with significant differences at five, 10, 15, and 120 min being lower in group A. Onset of analgesia and time for maximum analgesia was significantly shorter in group A. There was a significant decrease in hemodynamic parameters from baseline in both groups. The fall in heart rate was significantly greater in Group A and at almost all the time intervals after baseline, diastolic blood pressure (DBP) was also lower in group A. Maternal motor blockade scores, the intensity of maternal sedation, the incidence of maternal complications, the duration of the first and second stage of labor, the rate of instrumental delivery and cesarean section, total analgesic dose and PCA bolus requirement, and neonatal Apgar scores did not show a significant difference between the two groups. ConclusionBoth dexmedetomidine and clonidine provide hemodynamically stable labor with a fall in heart rate and maternal blood pressure in the initial hours. Dexmedetomidine has the advantage of faster onset of analgesia and time for maximum analgesia.
