Background: The hand is one of the most common parts of the body involved in burns, i.e., 80%. Even minor burns in the hand may result in severe limitations of function. Early initiation of physiotherapy, topical antibiotic cream treatment, collagen application, splintage, passive exercise for second-degree superficial burns. Materials and methods: A prospective comparative study was conducted in 10 patients with acute hand burns due to thermal burns (scald, flame). All patients with second-degree superficial to intermediate thickness burns were given Negative pressure wound therapy (indigenous NPWT Kit) to one hand and local antibiotic cream to the other hand or other parts of the body to study clinical profile and outcome. Results: A total of 10 patients were studied. The majority of patients were in 19 to 30 years of age group 6 patients (60%), five females, and one male. Pediatric patients account for 4 patients (40%), two female and two male children. Incidence of burns in females 70% and males’ group 30%. Significant reduction in postburn edema in NPWT hand compared to topical antibiotic cream dressing. Healing is fast in NPWT applied hand/part. Conclusion: Negative Pressure Wound Therapy for Acute second-degree superficial burns showed promising results in wound healing and reduced post-burn edema burn in hand in our study.

Abstract Introduction Peri-prosthetic joint infection (PJI) was one of the main causes of revision of arthroplasty. In order to reduce wound complications and surgical site infections, close incisional negative pressure wound therapy (ciNPWT) has been introduced into arthroplasty. This study was designed to review the clinical benefits of the application of ciNPWT in revision arthroplasty. Methods This was a single-centre retrospective comparative study approved by the Institutional Review Board. Patients, who underwent revision total knee arthroplasty or revision total hip arthroplasty at the author’s institution from January 2016 to October 2019, were included in this study. The ciNPWT cohort included all eligible patients, who underwent operations from January 2018 to October 2019, with the use of ciNPWT(n = 36). The control cohort included all eligible patients, who underwent operations from January 2016 to December 2017 with the use of conventional dressing(n = 48). The incidences of wound complications were compared to both cohorts. Results There was a statistically significant difference in the rate of superficial surgical site infection (SSI) between control cohort and ciNPWT cohort (12.5% in control vs 0% in ciNPWT, p = 0.035). However, there was no statistically significance of the overall wound complication rate for both cohorts. (14.6% in control vs 8.3% in ciNPWT, p = 0.504). Conclusions The application of ciNPWT could result in a lower rate of superficial surgical site infection when compared with conventional dressing among the patients undergoing revision total knee and total hip arthroplasties.

Insight Into

This report provides a simplified insight into the previously unexplained physical mechanism of the origin of local positive tissue pressure during negative-pressure wound therapy (NPWT). A chain of 2 spring model could be used to show the biomechanical interaction between the NPWT dressing and the adjacent body tissues. It is important to assume that the application of NPWT dressing to the body surface creates a new closed compartmentalized volume. Air suction generates local positive pressure within the dressing due to unopposed atmospheric load, which in turn leads to compression of the adjacent tissues and induction of positive pressure there. Analysis of the biomechanical events during NPWT implies the possibility of tissue injury by positive pressure and suggests clinical alertness in regard to the balance between the size of the NPWT dressing and suction pressure as well as further related research.

Life Patterns

Instant life patterns and eating patterns and inappropriate exercise schedules are thought to be one of the causes of the increasing number of diabetes mellitus. Complications that can be caused by this disease are in the form of excessive susceptibility to infection, so that it develops into diabetic ulcers and can lead to amputations in these parts of the body. The purpose of this study is to design a tool used to treat diabetic ulcers. The contribution of this study is that the system can help remove fluid from the wound with controlled suction pressure so that it can facilitate the healing process faster. This Negative Pressure Wound Therapy (NPWT) tool works based on negative pressure from the vacuum motor by utilizing MPXV4115VC6U and MPXV5050VC6T1 pressure sensors at a pressure limit of 0 to -350 mmHg. Using an Arduino microcontroller for data processing, it will then be displayed on the 2x16 LCD. The MPX4115VC6U sensor produces a pressure of -55.97 mmHg when setting -50 mmHg and the resulting output is 3.32 volts, while the MPXV5050VC6T1 sensor produces a pressure of 51.18 mmHg at a setting of 50 mmHg and the resulting output is 3.18 volts, from the above data it can be seen if the MPX5050VC6TI sensor has a smaller error given
