RESUMEN
Background: Worldwide disasters are a common event nowadays. A disaster is an incident that can cause massive disruption and damage. Disaster can be dramatically affected many people, either directly or indirectly. The affected people may die, injures and it also destroyed their houses, health system, and interrupted their lifeline. The study was aimed to identify the perceptions of knowledge regarding disaster management among healthcare workers in Bangladesh.Material and Methods: A total of 120 healthcare workers were selected to participate in this study using two stages of sampling technique. The study was carried out using a cross-sectional survey in the two selected medical college hospitals in Dhaka city of Bangladesh within a period of 4 months (January 2017–April 2017). The data were collected using a pre-tested self-administered semi-structured questionnaire and were analyzed using the Statistical Package for the Social Sciences ver-20.0.Results: In the present study, the mean age of the study respondents was 34.07 ± 10.64 years. About 51.7% of the study participants were female. Two-fifths (40%) of the study participants had diploma in radiology/pharmacy followed by B.Sc. in medical technology (20.8%) and MBBS (10.8%). More than three-fifths (64.2%) had < 11 years of professional experience.Conclusion: The level of good perception of knowledge of females was slightly higher than that of males. The doctors were found to have higher level of good perception of knowledge than those from other professions. The finding reported that close to nine-tenths of the study participants had good perception of knowledge regarding disaster management and the profession of the study participants was found significantly associated with the perception of knowledge regarding disaster management.
RESUMEN
Intubation in the lateral position is desirable in several conditions. We compared the technical ease and hemodynamic response to laryngoscopy and intubation in the lateral [group L] and supine [group S] positions in 120 patients with normal airway in a prospective randomized controlled study. This was a randomized, controlled observational study. All intubations were performed by a single investigator experienced in lateral intubation. Ventilation score with bag and mask ventilation, laryngoscopy duration and attempts, application of external pressure and Cormac and Lehane grade were measured. Blood pressure and heart rate were observed before and after induction of anesthesia, after laryngoscopy/intubation and then at one minute interval for 6 minutes. 90% of patients in group S were ventilated by a single operator compared to 17% in group L. Duration of laryngoscopy was significantly longer in group L [32 seconds] compared to group S [12 seconds] [p<0.001]. 78% of the patients in group S had Cormack and Lehane grade 1 versus nil in group L. External pressure was required in 58% patients in group L and 5% in group S. In intra-group comparison at specified time lines no difference was observed in HR but the changes in BP were significantly higher in the lateral position [P-value <0.001]. Ventilation and intubation in lateral position was more difficult technically than in the suprine position, and the BP response was exaggerated in the lateral position
