Randomized Controlled Trial
Efficacy of prophylactic intramuscular ephedrine in prevention of hypotension during caesarean section under spinal anaesthesia: a comparative study.
Hypotension during caesarean section under spinal anaesthesia is a common complication. Several measures are used to reduce the incidence of hypotension but no method is fully effective. Prophylactic intramuscular ephedrine may be effective in reducing the incidence of hypotension in addition to conventional measures. ⋯ Mean arterial pressure and heart rate were significantly more in group E10 compared to group C. No significant increase in the incidence of hypertension and tachycardia in any group were observed. The findings of this study indicate that prophylactic IM ephedrine 0.5 mg/kg given 10 minutes before spinal anaesthesia gives better haemodynamic stability during intra-operative period without any significant increase in the incidence of adverse effects.

Randomized Controlled Trial Comparative Study
Comparison of palanosetron, granisetron and ondansetron as anti-emetics for prevention of postoperative nausea and vomiting in patients undergoing middle ear surgery.
The objective of the study was to compare the efficacy of palanosetron (0.25 mg), granisetron (3.0 mg) and ondansetron (8.0 mg) used as anti-emetics for the prevention of postoperative nausea/vomiting in patients undergoing middle ear surgery. The study was done among 75 adult patients (age group 30-45 years) of which 50 were males and rest (25) females, all of ASA I and ASA II. The patients were randomly allocated into 3 equal groups: Group I (n = 25) received injection palanosetron (0.25 mg) IV, group II (n = 25) received injection granisetron (3 mg) IV and group III (n = 25) received injection ondansetron (8.0 mg) IV at the end of the surgical procedure. ⋯ The incidence of emesis-free patients during the 0-6 hours period was 100% for group I; 72% for group II and 56% for group III. During the 6-24 hours period incidence of emesis-free patients were 96% for group I; 56% for group II and 32% for group III. So to conclude, a single dose of palanosetron (0.25 mg) is a superior anti-emetic to granisetron (3.0 mg) or ondansetron (8.0 mg) in complete prevention of postoperative nausea and vomiting after middle ear surgery during the first 24 hours period.

Red cell distribution width (RDW) is an automated laboratory determination of red cell anisocytosis. The aim of the study was to analyse the role of RDW in differentiating iron deficiency anaemia (IDA) from thalassaemia trait. There were 500 patients who were screened for the study. ⋯ Evaluation of RDW as screening test to detect microcytic anaemia had sensitivity of 71.42% and specificity of 40%, Evaluation of RDW as a screening test for IDA had sensitivity of 67.9% and specificity 25%. It was found uniform increase in RDW in all cases of microcytosis. It is concluded that RDW adds useful but limited information in classifying microcytic anaemia.

Joubert syndrome is a very rare disorder characterised by respiratory irregularities, saccadic eye movements, hypotonia, ataxia, developmental retardation with abnormalities of cerebellum and brainstem. Epilepsy is rarely associated with this syndrome. Herein such a case with associated epilepsy is presented. ⋯ Pregnancy and prenatal period was uneventful. There was history of one of his siblings having the disorders of respiratory irregularities, saccadic eye movements, ataxia, hypotonia, etc (same as the child) and died at 3 1/2 years of age. MRI brain showed features of Joubert syndrome.

Randomized Controlled Trial Comparative Study
A comparative study of duration of postoperative analgesia between epidural bupivacaine and epidural clonidine plus bupivacaine in lumbar laminectomy surgery under general anaesthesia.
A randomised prospective double-blind placebo controlled study was undertaken in 60 patients of ASA-I and II, scheduled for lumbar laminectomy under general anaesthesia using thiopentone, fentanyl, artracurium, N2O/O2 and isoflurane. After obtaining written Informed consent from all patients, they were randomly allocated to two equal groups ie, group A (n = 30) and group B (n = 30). Group A patients received clonidine 0.5 ml (75 microg) plus 5 ml 0.25% bupivacaine and group B patients received 5 ml 0.25% bupivacaine plus 0.5 ml of normal saline (NS) as a control through epidural route placed by the surgeon at the closure of the surgery. ⋯ No clinically significant difference was found in heart rate, blood pressure, respiratory rate, oxygen saturation and motor blockade. Sedation score was slightly higher in group A, which was not significant. So small dose of clonidine (75 microg) as an adjuvant to 5 ml 0.25% bupivacaine in epidural route following lumbar laminectomy significantly prolonged postoperative analgesia and improved patient satisfaction without any clinically significant adverse reaction.
