Effect of pre-operative patient anxiety on post-spinal shivering during elective cesarean delivery: a prospective observational study
Authors' conclusion
High pre-operative anxiety and younger patient age were independent risk factors for post-spinal shivering during elective CD.
Study context
- Population
- Patients ≥18 years scheduled for elective cesarean delivery (CD) under spinal anesthesia
- Participants
- 150 patients
- Exposure
- High vs lower pre-operative anxiety
- Outcome
- Post-spinal shivering in relation to pre-operative anxiety (visual analogue scale (VAS) and APAIS)
