“A total of 404 patients from 34 geographically diverse institutions were included (mean age 58 ± 22 years, males 59%, pediatric 8%). During RSI, 21%, 87%, and 77% received pre-induction, induction, and paralysis, respectively. Significant differences in medication use by provider type were seen. Etomidate was administered to 58% with sepsis, but was not associated with adrenal insufficiency. Ketamine was associated with hypotension post-RSI [RR = 1.78 (1.36–2.35)] and use was low with traumatic brain injury/stroke (1.5%). Succinylcholine was given to 67% of patients with baseline bradycardia and was significantly associated with bradycardia post-RSI [RR = 1.81 (1.11–2.94)]. An additional 13% given succinylcholine had contraindications. Sedation practices post-RSI were not consistent with current practice guidelines and most receiving a non-depolarizing paralytic did not receive adequate sedation post-RSI.”

Results: Patients who received regional anesthesia had the shortest postoperative length of stay (0.67 [standard deviation: 2.0] days) compared to monitored anesthesia care/intravenous (IV) sedation (0.77 [1.8] days) and general anesthesia (1.44 [2.8] days). Administration of regional anesthesia was associated with a shorter length of stay compared to general anesthesia (odds ratio [OR]: 0.55, P = .001). Patients who received monitored anesthesia care/IV sedation had a lower risk of reoperation compared to general anesthesia (OR: 0.65, P = .012) but not compared to regional anesthesia (OR: 0.89, P = .759). Anesthesia type had no significant effects on other measured postoperative complications. Predictors of the type of anesthesia were age and surgical procedure as defined by Current Procedural Terminology code ( P < .001).

It is widely accepted that the central mechanism of postoperative NPPE is related to rapid negative intrapleural pressure increasing due to forceful inspiration against the obstruction, which can be up to 10 times or more that of normal breathing.  A typical event leading to acute airway obstruction associated with postoperative NPPE is laryngospasm. Other procedure that increases the risk of NPPE includes oropharyngeal, head, and neck surgery. Five [8–12] of the reported 29 cases involved upper respiratory tract surgery, and 10 [1,3,6,7,13–18] of the cases involved head and neck surgery, which may be related to tissue swelling and the sensitive dilator muscle of the upper airway in head and neck surgeries.
Gulur P, et al. Retrospective analysis of the incidence of epidural haematoma in patients with epidural catheters and abnormal coagulation parameters. Br J Anaesth. 015;114(5): 808–811.
“Results: During the study period, 11 600 epidural catheters were placed. In the setting of abnormal coagulation parameters, 278 (2.4%) epidural catheters were placed and 351 (3%) were removed. Two epidural haematomas occurred; both patients had epidural catheters and spinal drains placed for vascular procedures with abnormal coagulation parameters after operatation. The haematomas occurred after removal of the catheters. Based on our study, the incidence of epidural haematoma in patients with abnormal coagulation parameters is 1 in 315 patients, with the lower limit of the 95% confidence interval at 87 and the upper limit at 2597.”

One discussion this week included the impact of abdominal binder on seroma formation.

Summary: Application of an abdominal binder is often part of a standard postoperative regimen after ventral hernia repair to reduce pain and seroma formation. However, there is lack of evidence of the clinical effects.
