Negative Pressure Wound Therapy on Closed Surgical Wounds With Dead Space: Animal Study Using a Swine Model.
Closed incisional wound surgery frequently leaves dead space under the repaired skin, which results in delayed healing. The purpose of this study was to evaluate the effect of negative pressure wound therapy (NPWT) on incisional wounds with dead space after primary closure by evaluating the fluid volume through the suction drain, blood flow of the skin, tensile strength, and histology of the wounds. ⋯ This study explains some of the mechanism for using NPWT in closed incision wounds with dead space. It demonstrates that NPWT significantly reduces drainage amount, increases skin perfusion, increases tensile strength, and has the tendency to promote collagen synthesis for closed wound with dead space indicating enhanced healing.

Preparation of Partial-Thickness Burn Wounds in Rodents Using a New Experimental Burning Device.
The manual application of hot water or hot metal to an animal's skin surface is often used to prepare burn wound models. However, manual burn creation is subject to human variability. We developed a new device that can control the temperature, time, and pressure of contact to produce precise and reproducible animal burn wounds and investigated the conditions required to prepare various burn wounds using our new device. ⋯ We demonstrated that partial- and full-thickness burn wounds can be precisely and reproducibly created with our new automated burning device.

ReviewFree Flap Monitoring Using Near-Infrared Spectroscopy: A Systemic Review.
Although free flaps have become a reliable technique, vascular occlusion remains a significant risk. Flap survival is closely linked to the time interval between the onset and surgical repair of a microvascular problem. The newly emerged near-infrared spectroscopy (NIRS) shows the characteristics of being noninvasive, continuous, easy to use, objective, and immediately reflective, possibly making it an ideal candidate for postoperative flap monitoring. ⋯ Near-infrared spectroscopy seems to be a highly suitable candidate for postoperative flap monitoring. Larger-scale, randomized, multicentric clinical trials are needed in the future.

Comparative StudyComparison of Extension Orthosis Versus Percutaneous Pinning of the Distal Interphalangeal Joint for Closed Mallet Injuries.
We compared a static extension orthosis with percutaneous pinning of the distal interphalangeal joint (DIPJ) for treatment of closed mallet injuries. After receiving counsel about treatment options, 44 patients (25 women and 19 men; mean age, 57 years) freely chose orthosis and 18 patients (5 women and 13 men; mean age, 51 years) chose pinning. Both the extension orthosis and the pin remained in place for 6 weeks; the pin then was removed, and the care in both groups was transitioned to nighttime orthosis use for an additional 6 weeks. ⋯ The techniques produce satisfactory correction of extensor lag and have high patient satisfaction. Pinning allows better correction of DIPJ extensor lag and results in a smaller degree of final extensor lag. Pinning is more expensive and may result in more DIPJ stiffness (ie, loss of active flexion), but it may be justified in certain patients (eg, medical professionals, food service workers) who would have difficulty working with an orthosis.

Perioperative Safety in Plastic Surgery: Is the World Health Organization Checklist Useful in a Broad Practice?
In October 2007, the World Health Organization (WHO) introduced the Safe Surgery Saves Lives Program, the cornerstone of which was a 19-item safe-surgery checklist (SSC), in 8 selected hospitals around the world. After implementation, death rates decreased significantly from 1.5% to 0.8% (P = 0.003), inpatient complications reduced from 11% to 7% (P < 0.001), as did rates of surgical site infection (P < 0.001) and wrong-sided surgery (P < 0.47), across all sites. On the basis of these impressive reductions in complications and mortality, our institution adopted the WHO SSC in April 2009, with a few additional measures included, such as assuring presence of appropriate implants and administration of preoperative antibiotics and thromboembolic prophylaxis. Our purpose was to evaluate the efficacy and applicability of the surgical safety checklist in a multisurgeon plastic surgery hospital-based practice, by analyzing its effect on morbidity and outcomes. ⋯ Although certain elements of the WHO SSC checklist are universal and should be adopted, certain specific aspects require modification to improve applicability in a plastic surgery-specific practice. This necessitates the creation of a surgical safety checklist specifically for plastic surgery as other surgical specialties have proposed.
