RESUMO
Background: A person is said to have a functional limitation when he/she does not have the physical or cognitive ability to independently perform the routine activities of daily living. If recognized at an early stage, these can often be improved greatly, helping them regain their functional abilities and independence. Objective: The objective of the study was to determine the prevalence of functional limitations among older adults in a rural area in south Kerala. Materials and Methods: The cross-sectional study was conducted among older adults residing in the field practice area of a rural health training center of a medical college in south Kerala for 3 months from October 2019 to December 2019. Data were collected by interview of the participants by the investigator. The modified Barthel Index for activities of daily living was used to determine the prevalence of functional limitations. Results: The overall prevalence of functional limitations among older adults in a rural area in south Kerala was 35.9%. The most common functional limitation experienced by the participants was difficulty in climbing stairs. Functional limitation was found to be significantly associated with the age, socioeconomic status, and type of family of the participants. Conclusion: There is an urgent need to focus on the functional limitation among older adults, especially among the oldest old and those in lower socioeconomic status with emphasis on the need to strengthen the health‑care facilities for them, with respect to early identification and management of their functional limitations.
RESUMO
Introduction: Hemodynamic responses during laryngoscopy can potentially precipitate ischemia in patients with coronary artery disease. There are conflicting reports regarding the hemodynamic stress responses between the conventional Macintosh and video laryngoscopes. There is a paucity of studies regarding the same in cardiac surgical patients. Materials and Methods: A prospective, randomized control study to compare the hemodynamic responses and ease of intubation using Airtraq video laryngoscope and Macintosh laryngoscope in patients with ischemic heart disease. Results: Seventy patients were randomized into two groups. Baseline variables including age, weight, Mallampati score, and comorbidities were comparable between the two groups. There was statistically significant elevation in mean heart rate in the Macintosh group at 2nd-min (P = 0.02) and 3rd-min (P = 0.05) postintubation. Similarly, there was a significant increase in mean arterial pressure at 2nd (P = 0.06), 3rd (P = 0.03), and 4th (P = 0.03) in the Macintosh group. The time for laryngoscopy and Intubation Difficulty Scale was significantly better in the Airtraq group (P = 0.001 and 0.001). However, the median time to intubation was longer in the Airtraq group (13 s vs. 11 s, P = 0.05). Laryngoscopy view was better with Airtraq even in patients with Mallampati score 3 (ten patients). The incidence of trauma was same in both the groups. Conclusion: Airtraq provides the better hemodynamic stability and ease of intubation and may be considered superior to conventional Macintosh laryngoscope for intubation in patients with ischemic heart disease.
RESUMO
Introduction: The search for an accurate and predictable method to estimate the endotracheal tube (ETT) size in pediatric population had led to derivation of many formulae. Of this, age-based formulae are the most commonly used. Studies have shown that minimal transverse diameter of subglottic airway (MTDSA) measurements using a high-frequency probe improves the success rate of predicting the airway diameter to about 90%. We did a prospective observational study using MTDSA as the criteria to select the size of ETT in children with congenital heart disease. Methods: In this prospective observational study, 51 children aged from 1 day to 5 years, scheduled for cardiac surgery, were enrolled for this study. The ETT size was guided solely based on the MTDSA. Leak test was used to determine the best-fit ETT size. Results: Data from 49 patients were analyzed. Agreement between the ETT determined by MTDSA and that predicted by Cole's age-based formulas with the best-fit ETT size was analyzed using a Bland–Altman plot. Conclusion: Age-based formula showed poor correlation (27.5%) compared to MTDSA (87.8%) in predicting the best-fit ETT. We observed that pediatric patients with congenital heart disease need a larger sized ETT as compared to what was predicted by age-based formula. Using ultrasound MTDSA measurements to guide selection of ETT size is a safe and accurate method in pediatric cardiac population.
RESUMO
The Arndt blocker is positioned in the desired bronchus using a wire loop which couples the blocker with a fiberoptic bronchoscope (FOB). The wire loop once removed cannot be reinserted in 5F and 7F blockers making repositioning of the blocker difficult. A 34-year-old female was to undergo left thoracotomy followed by laparoscopic cholecystectomy. The left lung was isolated with a 7F Arndt bronchial blocker. During one‑lung ventilation, the wire loop was removed for oxygen insufflation. There was loss of lung isolation during the procedure and dislodgement of the blocker was confirmed by FOB. The initial attempts to reintroduce the blocker into the left main bronchus failed. An alternative technique using a glide wire was attempted which resulted in successful reintroduction of the Arndt blocker. The 0.032 inch zebra glide wire may be effectively used to reposition a dislodged Arndt blocker if the wire loop has been removed.
