Inferior Vena Cava Collapsibility Index Assessment in Predicting Post Spinal Anaesthesia Hypotension in Patients Undergoing Arthroscopic Knee Surgeries.

Inferior Vena Cava Collapsibility Index Assessment in Predicting Post Spinal Anaesthesia Hypotension in Patients Undergoing Arthroscopic Knee Surgeries.

The aim of this study was to evaluate the role of inferior vena cava collapsibility index assessment in predicting post spinal anaesthesia hypotension in patients undergoing arthroscopic knee surgeries.

Prospective Cohort Study conducted in Ain Shams University Hospitals.

Inclusion Criteria:

• Patients: American Society of Anesthesiologists Physical Status (ASA) I to II undergoing arthroscopic knee surgeries under spinal anaesthesia.
• Both Sexes.
• Aged 30 to 60 years.
• Body mass index <35 kg/m2

Exclusion Criteria:

• Patients' refusal of procedure or participation in the study.
• Patients with contraindication to spinal anaesthesia.
• Patients with severe cardiovascular or pulmonary disease.
• Patients with pre-procedural hypotension (systolic arterial pressure less than 90 mmHg and/or mean arterial pressure less than 60 mmHg).
