ABSTRACT
The current Study was done to compare the efficacy of intravenous lignocaine 2% versus oropharyngeal topical 10% xylocaine spray before induction of anaesthesia in attenuating the pressor response to direct laryngoscopy and endotracheal intubation. A total of 60 patients were divided randomly into two groups of 30 patients each. Group I received intravenous lignocaine 2% @ 1.5 mg/kg. Group II received topical 10% xylocaine spray @ 1.5 mg/kg body weight just before induction of anaesthesia. All hemodynamic parameters were measured immediately after laryngoscopy and intubation and at 1, 3, 5 minutes after laryngoscopy and intubation in both the groups. Mean values of haemodynamic parameters in Group I increased after intubation and then started declining but did not reach the baseline even at 5 minutes. In Group II all mean values of haemodynamic parameters increased after intubation and then started declining to almost baseline at 5 minutes. The differences in mean values of haemodynamic between the two groups immediately after intubation and at 1, 3 and 5 minutes thereafter were statistically highly significant (p<0.001). Oropharyngeal topical xylocaine 10% when applied before induction of general anaesthesia is more effective method for attenuating the pressor response to direct laryngoscopy and endotracheal intubation when compared to intravenous lignocaine 2%
ABSTRACT
Xanthogranulomatous cystitis (XC) is a rare benign chronic granulomatous inflammation of the urinary bladder of unknown etiology. Here, we report a rare case of XC in a 54-year-old man who presented with painless hematuria and frequent urination for the past 3 years. His urine culture and sensitivity were positive for Escherichia coli with significant colony count. Contrast-enhanced computed tomography showed diffusely thickened urinary bladder with no definitive mass. The patient was subjected to other investigations including cystoscopy and biopsy. All the above investigations confirmed the entity to be XC. An endoscopic resection was performed and he was started on a sulfamethoxazole-trimethoprim combination. The patient was asymptomatic at 3-month follow-up.
ABSTRACT
The aim of the present study was to evaluate the effects of partial sleep deprivation on the cognitive status and alertness of medical students using auditory event related potential (ERP) and auditory reaction time (RT) using sleep questionnaire, Stanford Sleepiness Scale (SSS), auditory ERP (P300) and RT. Sleep time was significantly shorter in the test condition as compared to the baseline values (p<0.001). Significantly higher values on the SSS (p<0.05) were found after sleep restriction. The P300 latency and amplitude significantly decreased (p<0.01 and p<0.001 respectively) when the test values were compared to the baseline. RT also showed a significant decrease (p<0.001) in the test condition as compared to the baseline values. However, no significant correlation could be ascertained between SSS and P300 amplitude and latency as well as RT. This study demonstrates that partial sleep deprivation produces variable effects on the cognitive status of medical students as reflected by the decrease in P300 amplitude and latency. Alertness of medical students seemed to show an improvement as reflected by the decrease in RT.
