Comparison of RAMP and New Modified RAMP Positioning in Laryngoscopic View During Intubation in Patients with Morbid Obesity: A Randomized Clinical Trial. | LitMetric

AI Article Synopsis

  • The study addresses the challenges anesthesiologists face when managing airways in obese patients, whose body composition can complicate intubation.
  • It compares a standard ramp position to a new low-cost modified ramp position for intubation during bariatric surgery, utilizing various metrics like laryngoscopic view and intubation duration.
  • Results indicate no significant differences in effectiveness between the two positions, suggesting the modified ramp is a viable, easier, and cheaper alternative.

Article Abstract

Background: The prevalence of obesity is increasing worldwide, and anesthesiologists are facing challenges in the airway management of such patients. Excessive adipose tissue influences pharyngeal spaces and affects the laryngoscopic grade. Standard ramp positioning is time-consuming and difficult to prepare, and requires expensive equipment.

Objectives: The aim of this study was to compare the standard ramp position with the proposed low-cost and easily accessible modified ramp position in laryngoscopic view during the intubation of patients with morbid obesity.

Methods: In this single-blind clinical trial, 84 patients candidate for bariatric surgery at Rasoul Akram Hospital in 2020 were assigned to the rapid airway management positioner (RAMP) (R) and new modified RAMP (MR) groups by the block randomization method. The laryngoscopic view of the glottis based on the Cormack-Lehane scale, ventilation quality, duration of intubation, intubation attempts, oxygen saturation at the end of intubation, and the need for backward, upward, rightward pressure (BURP) maneuver for successful intubation were recorded. Normal distribution tests and Mann-Whitney and Kruskal-Wallis tests were used to analyze the data.

Results: The results showed no significant differences between the two groups regarding ventilation score, laryngoscopy grade, number of intubation attempts, duration of intubation, and the need for BURP maneuvers during intubation (P > 0.05).

Conclusions: The two methods are not significantly different, and the new modified ramp position can be used with more ease and availability and less cost.
