ABSTRACT
Background: The usefulness of modified Cormack-Lehane scoring system (MCLS) used for laryngoscopy was introduced and used extensively Western population. This study was undertaken for evaluation of modified Cormack-Lehane scoring system in Indian population. Methods: 198 patients of more than 18 years of age requiring tracheal intubation were evaluated with preoperative airway predictors, the modified Mallampati test and thyromental distance (TMD). Result: The larynx was difficult to visualize (Cormack and Lehane grades IIIB and IV) in 18 / 198 (9.09 %) patients. No failed tracheal intubations occurred in any of the 18 cases. Conclusion: The Mallampati classification was associated with good predictive value for 3B and 4 of modified Cormack-Lehane scoring system. The MCLS better delineates the difficulty experienced during laryngoscopy than the original Cormack-Lehane grading.
ABSTRACT
Background: This study was planned with an aim to compare duration of analgesia produced by intrathecal bupivacaine and intrathecal buprenorphine with intrathecal bupivacaine and femoral and sciatic nerve blocks. Methods: Patients were randomly divided in two groups, 25 in each and labelled Group – A (Buprenorphine ) and Group – B ( Nerve blocks ) duration of analgesia produced was compared. Results: The mean duration of post operative pain relief in Group A was 5.70 ± 0.90 hours (342.00 Min ± 52 Min). While in Group B it was 11.26 ± 1.20 hours, (675.60 ± 72 min). Conclusion: Nerve blocks (femoral & sciatic) are extremely useful, safe, effective and reliable method for producing post operative pain relief.
ABSTRACT
Background: This study has been done to compare Hyomental distance with the modified Mallampati test, Thyromental distance for accurately predicting difficult visualization of the larynx in apparently normal patients’. Methods: 198 apparently normal patients of > 18 years of age, with ASA 1 and 2, undergoing general anaesthesia with tracheal intubation were evaluated. A hard-plastic bond ruler is used to measure the distance. After induction and paralysis using glottic visualisation was assessed by using modified Cormach and Lehane classification with no external laryngeal manipulation. Results: The highest sensitivity of 44.44 % was observed in predicting difficult visualization of the larynx with modified Mallampati followed by TMD 11.11 % and HMD 11.11 % (2/18). Conclusion: An optimal combination of tests that includes the HMD,MMT,TMD and other predictors and performing the tests in combination for predicting Difficult Laryngoscopy, rather than using it alone.
