Why the study?

Does subarachnoid block reduce deep vein thrombosis, blood loss, and hypoxaemia compared to general anaesthesia in elderly patients undergoing emergency hip surgery?

Key Points

To compare clinical outcomes, including deep vein thrombosis, blood loss, hypoxaemia, and mortality, between subarachnoid block and general anaesthesia in elderly patients undergoing emergency hip surgery.
Randomized trial involving 132 elderly patients undergoing emergency hip surgery allocated to receive either a subarachnoid block (SAB) or general anaesthesia (GA).
Assessed deep vein thrombosis using the 125I-fibrinogen uptake test, alongside measurements of blood loss, arterial oxygen tension (PaO2), and postoperative mortality.
Deep vein thrombosis developed in 17 of 37 patients in the SAB group versus 30 of 39 patients in the GA group (P = 0.05).
Mean blood loss was significantly lower in the SAB group at 513 ml (± SEM 44) compared to 714 ml (± SEM 67) in the GA group (P < 0.01).
Immediate postoperative decrease in PaO2 was 0.16 kPa following SAB compared to 0.86 kPa following GA (P < 0.01), whereas mortality differences (3 SAB vs 9 GA) were not statistically significant.

Population

132 elderly patients undergoing emergency hip surgery

Intervention

Subarachnoid block (SAB) / spinal anaesthesia

Subarachnoid block significantly reduces the incidence of deep vein thrombosis and blood loss compared to general anaesthesia in elderly patients undergoing emergency hip surgery.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Supports subarachnoid block over general anaesthesia to reduce deep vein thrombosis in elderly hip surgery; extends evidence favoring regional techniques in high-risk patients.
