Comparison the Hemodynamic Responses to Laryngoscopy and Tracheal Intubation with Glidescope or Macintosh Laryngoscope in Severe Preeclamptic Patients Undergoing Cesarean Delivery

Abstract

The aim of this study was comparison the hemodynamic responses to laryngoscopy and tracheal intubation with Glidescope or Macintosh laryngoscope in severe preeclamptic patients undergoing cesarean delivery. Materials and Methods: In this clinical trial, 70 preeclamptic parturents, gestational age ≥ 34 weeks, and scheduled for cesarean delivery, undergoing general anesthesia with endotracheal intubation were studied. Tracheal Intubation was performed using by Glidescope (study group; n=35) or Macintosh Laryngoscope (Control group; n=35). Hemodynamic parameters were compared between two groups after the induction of anesthesia, laryngoscopy, and tracheal intubation. Results: Frequency of increased blood pressure after tracheal intubation was significantly lower in the study group (11.4 %) than the control group (31.42%) (p=0.006). The mean of systolic blood pressure was significantly smaller in the study group at 1 (136.82±15.59 vs 156.80±20.64 mmHg; p=0.001), 2 (127.54±17.39 vs 148.14±16.42 mmHg; p=0.002) and 3 (128.82±11.05 vs 142.82±12.13mmHg; p=0.003) minutes.
