Article Notes
This prospective observational study across eight Canadian hospitals identified post-operative residual paralysis in 64% of patients at extubation and 57% on arrival in the PACU, despite more than 70% of patients receiving reversal with neostigmine.
Rocuronium was the muscle relaxant used in 99% of cases.
This retrospective propensity-matched cohort study, used 5 years of data to study 2,644 matched pairs-of-patients with a preoperative diagnosis of severe COPD.
Important exclusions were patients already ventilated, already with pulmonary infections, along with cardiac, emergency & transplant surgery, and those receiving repeat surgery within 30 days.
Receiving general anesthesia was associated with a 43% higher risk of respiratory infection (3.3% vs 2.3%, P = 0.0384), 133% greater risk of prolonged ventilation (2.1% vs 0.9%, P = 0.0008) and 44% greater risk of unplanned post-op intubation (2.6% vs 1.8%, P = 0.0487), when compared with regional anesthesia.
Nonetheless there was no significant mortality difference at 30 days (3.0% vs 2.7%, P = 0.6788).
The mix of regional techniques was 341 epidural, 1713 spinal, and 590 peripheral blocks. Notably, sub-group analysis of epidural-patients showed no difference in pulmonary complications or composite morbidity between epidural and general anesthesia. (Though given relatively small number of epidural patients, this might reflect a lack of power).
This retrospective audit identified an association between the introduction of unrestricted access to sugammadex and a fall in 'anaesthetic theatre time'. Mean hospital stay was also observed to be 0.8 days shorter after introduction of sugammadex, but was not statistically significant after adjusting for confounders.
Ledowski et al. investigated the effect of unrestricted access to sugammadex in an Australian teaching hospital with a retrospective observational audit.
Use of both sugammadex and amino steroid relaxants increased dramatically, with average reversal costs per case increasing by AUS$85.
Although there was no change in anaesthesia, surgical or PACU time, there was a statistically significant decrease in median time from surgery to hospital discharge (0.2 days shorter) after introduction of sugammadex. Do to the nature of the study, it is nevertheless impossible to infer a causal link.
