Background: Mechanical stimulation of airway structures occurs during laryngoscopy. The magnitude of cardiovascular response is related to the force and duration of laryngoscopy. Video laryngoscopes like Airtraq ® will help us to intubate patients with restricted neck movements without much manipulation but are bulkier than conventional Macintosh laryngoscope. We compared Airtraq ® and Macintosh laryngoscopes in patients with simulated cervical spine injury with respect to haemodynamic fluctuations. Methodology: A prospective, randomized study involving patients who are undergoing elective surgical procedures under GA. After routine preoperative preparation and monitoring, patients were administered conventional general anaesthesia. Preloaded Airtraq ® or Macintosh laryngoscope was used for intubation. The outcome variables of heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were recorded at regular intervals. Duration for intubation, manoeuvers required to optimize laryngeal view, glottic view, number of attempts taken and complications if any, were noted down as secondary objectives. Results: We observed that there is no significant difference in the average of variation in HR (p=0.078), SBP (p=0.515) and MAP (p=0.057) from the baseline between the two groups. We performed independent sample t test to know whether there is any significant difference for average duration of intubation, glottic view, ease of intubation and complications and we observed that there is significant difference in average duration of intubation (p=0.002) between two groups. Conclusion: Haemodynamic response caused by intubation with Airtraq ® and Macintosh laryngoscopes in simulated cervical spine injury were comparable.
Introduction: Chronic obstructive pulmonary disease (COPD) is associated with intermittent exacerbation with deterioration in their symptoms of dyspnoea and cough with expectoration. These patients often require repeated hospitalisation for the control of these exacerbations. Repeated hospitalisation can have persistent psychological effects on these patients. Methodology: This was a prospective, observational study. Twenty nine patients admitted to the medical intensive care unit (ICU) with a diagnosis of COPD were enrolled. They were assessed for anxiety and depression using hospital anxiety and depression scale (HADS). Hospital anxiety and depression questionnaire were addressed to patient twice: once just before discharge from ICU and again just before discharge from ward and the results were compared. Result: Out of twenty nine patients, 8 (27.5%) showed anxiety, 6 (20.6%) patients were having borderline anxiety and 15 (51.7%) patients had no anxiety. Ten (35%) patients showed depression, 13 (45%) patients had borderline depression and 6 (20%) patients had no depression during intensive care management. In the ward, the same patients were assessed again for anxiety. Five (17.2%) patients showed anxiety, 10 (34.8%) patients had borderline anxiety and 14 (48.2%) patients had no anxiety during ward stay. Similarly, four (13.7%) patients showed depression, 13 (44.8%) patients had borderline depression and 12 (41.3%) patients had no depression. Conclusion: Anxiety and depression is common in COPD patients and it is more during ICU stay compared to ward stay.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
