This retrospective study examined Total Intravenous Anesthesia (TIVA), volatile inhalational anesthesia, and analgesic techniques of epidural or paravertebral block. Lung resection was the specific focus.
The aim was to investigate the influence of anaesthetic and analgesic technique on the need for unplanned postoperative intensive care admission – defined as the unplanned need for either tracheal intubation and mechanical ventilation or renal replacement therapy.
It was found that patients having TIVA or epidurals were less likely to have an unplanned admission to intensive care.
Mortality and length of stay was higher in those needing unplanned ICU admission.
The study discusses possible mechanisms for these findings but emphasizes that prospective randomized trials are needed to prove causation.
