“…16 Interestingly, in our study, the trend towards more inadequate spinal anaesthesia in the low-dose group occurred despite an acceptable median (IQR) peak sensory level, using ethyl chloride cold spray, of T8 (8-10) for the required surgery. This suggests that the quality of surgical anaesthesia for any given procedure cannot be predicted entirely by the peak sensory level achieved, as assessed by cold sensitivity.…”

“…Sensory levels were assessed according to the following scale 8 :  0= an ability to appreciate a pinprick as sharp  1=perception of a pinprick as less sharp as unblocked areas  2=perception of a pinprick as touch but not sharp (analgesia)  3=an inability to feel pinprick (anaesthesia) Surgery was allowed to start when scale was>or=2 assessed at or above T12. Sensory block assessments were performed 5, 10, 15 and thereafter every 15 minutes till two segment regression was achieved.…”

BACKGROUNDTotal knee replacement is a surgical procedure in which parts of knee joint are replaced with artificial prosthesis so as to relieve pain and function of an arthritic knee. It is usually performed in geriatric patients under regional anaesthesia. In developing countries like India, majority of older population are overweight or obese according to standard body weight criteria. The aim of this study was to find out the association between body mass index and duration of spinal anaesthesia in adults undergoing total knee replacement arthroplasty.

Background: Spinal anesthesia is the preferred anesthetic technique for cesarean deliveries. But there is a dosage dilemma regarding block to the desired level and preventing hypotension. We aim to study effects of fixed dose with height and weightadjusted dose of intrathecal 0.5% hyperbaric bupivacaine during elective cesarean section. Methods: Eighty-eight singleton term parturients were enrolled and divided into two groups, Group FD (Fixed Dose) and CD (Calculated Dose) in this prospective, double-blind, randomized controlled trial. Group FD received 2.2 ml and CD received a height and weight adjusted calculated dose based on Harten's chart. Hemodynamic changes, onset time to sensory block to T6, maximum block in 20 minutes, and adverse effects were compared. Results: There was a significant reduction in median drug dosage of 11mg in FD versus 9 mg in CD group. The decrease in the MAP was less in group CD (14.5±2.98) mmHg compared to (17.6±4.66) mmHg in group FD (P= 0.03). The median onset time of spinal block to T6 in group FD of 2 minutes with IQR (2-3) was faster than Group CD 4 minutes with IQR (3-5). The spinal block extended above T4 in the larger number of parturients 23 (52 %) in Group FD than in three (6.8%) in group CD (p<0.05).Significantly larger number 20 (45.45 %) in group FD developed hypotension than seven (15.9 %) in Group CD. Bradycardia and vomiting were also found in group FD. Conclusions: This calculated dose provided the desired level of the spinal block and also restricted spinal block level with a distinct advantage of less hypotension.
