简要总结

This study aims to compare the efficacy of intravenous dexmedetomidine infusion versus virtual reality (VR) in reducing maternal anxiety, stress, and hemodynamic instability during cesarean section and their effects on neonatal outcome as respiration and heart rate.

详细描述

Cesarean section (CS) is one of the most frequently performed surgical procedures worldwide, with steadily increasing rates across both developed and developing countries.

Dexmedetomidine, a highly selective α₂-adrenergic receptor agonist, has been increasingly utilized in obstetric anesthesia because of its anxiolytic, sedative, and analgesic properties with minimal respiratory depression.

Non-pharmacological interventions, such as virtual reality (VR), have emerged as innovative strategies for perioperative anxiety management. VR provides immersive distraction, thereby modulating pain perception and reducing stress.

研究组 & 干预措施

Dexmedetomidine group

Experimental

Following confirmation of adequate spinal anesthesia, dexmedetomidine will be administered as an intravenous infusion of 0.2-0.4µg/kg/hr until abdominal closure.

干预措施: Dexmedetomidine (Drug)

Virtual reality group

Experimental

Participants will be fitted with virtual reality headsets immediately after the establishment of spinal anesthesia. The headsets will display calming immersive audiovisual content, and participants will continue wearing them throughout the entire procedure until skin closure.

干预措施: Virtual reality (Other)

结局指标

主要结局

Maternal anxiety

时间窗: Two hours postoperatively in the recovery room

Maternal anxiety will be assessed at three time points (On admission to the operating theatre, At skin suturing, Two hours postoperatively in the recovery room) using the Novel Visual Facial Anxiety Scale (NVFAS), a validated pictorial self-report measure. NVFAS will be applied to measure acute state anxiety. This self-reported pictorial tool consists of 11 facial expressions corresponding to anxiety scores from 0 (no anxiety) to 10 (severe anxiety). The scale is user-friendly, language-independent, and has been validated for perioperative patients, including those with limited time for traditional questionnaires.

次要结局

  • Heart rate(24 hours postoperatively)
  • Mean arterial pressure(24 hours postoperatively)
  • Peripheral Oxygen Saturation(24 hours postoperatively)
  • Stress Level(Two hours postoperatively in the recovery room)
  • Maternal Satisfaction(Two hours postoperatively in the recovery room)
  • Apgar score(5 minutes postoperatively)
