Air leaks after lobectomy are associated with increased length of stay (LOS) and protracted resource utilization. Portable drainage systems (PDS) allow for outpatient management of air leaks in patients otherwise meeting discharge criteria. We evaluated the safety and cost efficiency of a protocol for outpatient management of air leaks with a PDS. ⋯ In patients otherwise meeting discharge criteria, outpatient management of air leaks is safe and effective. This strategy is associated with improved efficiency of postoperative care and a modest reduction in hospital costs. This model may be applicable to other thoracic procedures associated with protracted LOS.

For appendicitis, single-incision laparoscopic appendectomy (SIA) has been proposed as an alternative to 3-port appendectomy (3PA). However, there remains controversy regarding outcomes and cost of SIA. We sought to review our experience with these two techniques to identify differences in these factors. ⋯ Our study suggests that SIA is a faster, more cost effective alternative than 3PA for acute appendicitis. SIA did not result in increased infection rates for acute or perforated appendicitis and can be considered an equivalent alternative to 3PA in the surgical management of appendicitis.

Randomized Controlled Trial
Site-directed topical lidocaine spray attenuates perioperative respiratory adverse events in children undergoing elective surgery.
Perioperative respiratory adverse events (PRAEs) are a major cause of morbidity and mortality associated with pediatric anesthesia. Topical lidocaine administration reduces risk of PRAE in children undergoing elective endotracheal intubation. However, definitive evidence of its efficacy remains elusive, due, in part, to the wide variability in the methodology for spraying topical lidocaine. In this randomized controlled double-blind clinical trial, we sought to evaluate the effect of site-directed topical airway lidocaine, sprayed directly onto supraglottic, glottis, and subglottic areas, on the incidence of PRAE. ⋯ Site-directed topical spray of lidocaine over supraglottic, glottis, and subglottic areas before tracheal intubation significantly reduced the incidence of PRAE and a prolongation of extubation time in children.

Multicenter Study Comparative Study
Do risk calculators accurately predict surgical site occurrences?
Current risk assessment models for surgical site occurrence (SSO) and surgical site infection (SSI) after open ventral hernia repair (VHR) have limited external validation. Our aim was to determine (1) whether existing models stratify patients into groups by risk and (2) which model best predicts the rate of SSO and SSI. ⋯ All five existing predictive models have limited ability to risk-stratify patients and accurately assess risk of SSO. However, both the VHRS and ACS-NSQIP demonstrate modest success in identifying patients at risk for SSI. Continued model refinement is needed to improve the two highest performing models (VHRS and ACS-NSQIP) along with investigation to determine whether modifications to perioperative management based on risk stratification can improve outcomes.

Respiratory rate (RR) is a critical vital signs monitored in health care setting. Current monitors suffer from sensor-contact failure, inaccurate data, and limited patient mobility. There is a critical need for an accurate and reliable and noncontact system to monitor RR. We developed a contact-free radio frequency (RF)-based system that measures movement using WiFi signal diffraction, which is converted into interpretable data using a Fourier transform. Here, we investigate the system's ability to measure fine movements associated with human respiration. ⋯ Initial clinical pilot trials with our contact-free RF-based monitoring system demonstrate a high degree of RR measurement accuracy when compared to capnographic data. Based on these results, we believe RF-based systems present a promising noninvasive, inexpensive, and accurate tool for continuous RR monitoring.
