Culture positivity correlated directly with the duration of open exposure of the uncovered operating-room trays. Light traffic in the operating room appeared to have no impact on the contamination risk. Coverage of surgical trays with a sterile towel significantly reduced the contamination risk.

More than 200,000 people in the United States are diagnosed annually with compartment syndrome. This condition is commonly established based on clinical parameters. Determining its presence, however, can be challenging in obtunded patients or those with an altered mental status. A delay in diagnosis and treatment of these injuries can result in significant morbidity. Surgical release of the enveloping fascia remains the acceptable standard treatment for compartment syndrome. This article reviews the evaluation and treatment of compartment syndrome.

Background The basic perineural catheter design has changed minimally since inception, with the catheter introduced through or over a straight needle. The U.S. Food and Drug Administration recently cleared a novel perineural catheter design comprising a catheter attached to the back of a suture-shaped needle that is inserted, advanced along the arc of its curvature pulling the catheter past the target nerve, and then exited through the skin in a second location. The authors hypothesized that analgesia would be noninferior using the new versus traditional catheter design in the first two days after painful foot/ankle surgery with a primary outcome of average pain measured with the Numeric Rating Scale. Methods Subjects undergoing painful foot or ankle surgery with a continuous supraparaneural popliteal-sciatic nerve block 5 cm proximal to the bifurcation were randomized to either a suture-type or through-the-needle catheter and subsequent 3-day 0.2% ropivacaine infusion (basal 6 ml/h, bolus 4 ml, lockout 30 min). Subjects received daily follow-up for the first four days after surgery, including assessment for evidence of malfunction or dislodgement of the catheters. Results During the first two postoperative days the mean ± SD average pain scores were lower in subjects with the suture-catheter (n = 35) compared with the through-the-needle (n = 35) group (2.7 ± 2.4 vs. 3.4 ± 2.4) and found to be statistically noninferior (95% CI, −1.9 to 0.6; P < 0.001). No suture-style catheter was completely dislodged (0%), whereas the tips of three (9%) traditional catheters were found outside of the skin before purposeful removal on postoperative day 3 (P = 0.239). Conclusions Suture-type perineural catheters provided noninferior analgesia compared with traditional catheters for continuous popliteal-sciatic blocks after painful foot and ankle surgery. The new catheter design appears to be a viable alternative to traditional designs used for the past seven decades.

BackgroundFollowing outpatient surgery, it is often difficult to provide adequate analgesia while concurrently minimizing opioid requirements. Ultrasound-guided percutaneous peripheral nerve stimulation has been proposed as an analgesic, but requires physician-level skills, advanced equipment, up to an hour to administer, and is frequently cost prohibitive. In contrast, percutaneous auricular neuromodulation may be placed by nursing staff in a few minutes without additional equipment, theoretically provides analgesia for nearly any anatomic location, lacks systemic side effects, and has no significant risks. We now present a case report to demonstrate proof of concept for the off-label use of an auricular neuromodulation device—originally developed to treat symptoms associated with opioid withdrawal—to instead provide analgesia following outpatient surgery.Case presentationFollowing moderately painful ambulatory orthopedic and breast surgery, seven patients had an auricular neuromodulation device (NSS-2 Bridge, Masimo, Irvine, California, USA) affixed within the recovery room in approximately 5 min and discharged home. Average resting and dynamic pain scores measured on the 0–10 Numeric Rating Scale were a median of 1 over the first 2 days, subsequently falling to 0. Five patients avoided opioid use entirely, while the remaining two each consumed 5 mg of oxycodone during the first 1–2 postoperative days. After 5 days, the devices were removed at home and discarded.ConclusionsThese cases demonstrate that ambulatory percutaneous auricular neuromodulation is feasible and may be an effective analgesic and decreasing or even negating opioid requirements following outpatient surgery. Considering the lack of systemic side effects, serious adverse events, and misuse/dependence/diversion potential, further study with a randomized, controlled trial appears warranted.

The optimal management of circumferential extremity burns remains a challenge. Elevation of the extremity to decrease wound swelling and avoid pressure at the point of contact on new skin grafts is a standard objective but can be frequently difficult to accomplish. Although various forms of elevation have been proposed, our purpose was to evaluate the safety and efficacy of the uniplanar external fixation (UEF) device in providing extremity elevation and stabilization while optimizing skin grafting. Intraoperative application of either upper or lower extremity UEF was performed at the time of eschar excision and application of split-thickness autografts. Inclusion criterion was that patients should be over 16 years of age with third-degree circumferential extremity burns that were planned for autologous skin grafting within 48 hours after their injury. Patient consent was obtained in every case. Eight patients aged 17 to 62 with circumferential extremity burns were reviewed. No pin-tract infections were observed, nor were any of the skin grafts lost due to shearing. Peripheral nerve and arterial injuries were not encountered. Only one patient with an oversized arm secondary to morbid obesity had a pin pull-out. No other patient developed adverse sequelae from the surgery or from the placement of the UEF device. The UEF device provides a safe and effective means for elevation of extremites in patients with circumferential extremity burns undergoing skin grafting. This allows for optimal access for skin grafting, dressing changes, and postoperative positioning. Shear injury and pressure necrosis of the fresh grafts is minimized. Increasing the number of pins in obese patients should be considered to avoid the complications of pin pull-out.
