Hypokalaemic Paralysis Associated with COVID-19 Infection.

INTRODUCTION: COVID-19 is a pandemic affecting mainly respiratory and gastrointestinal system. Severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) binds angiotensin converting enzyme 2 (ACE-2) of renin-angiotensin system (RAS) resulting in hypokalaemia. We hereby report the a of hypokalaemic paralysis induced by COVID-19. CASE: A 56 years old male with no co-morbidities presented with fever (2days), weakness in bilateral lower limbs (1 day). His had severe hypokalaemia with serum potassium of 2.05 mEq/L. RT-PCR of nasopharyngeal swab for SARS-CoV- 19 was positive. He was diagnosed as a case of hypokalaemic paralysis induced by COVID-19 infection. CONCLUSION: We suggest that during this pandemic era if a COVID-19 patient presents with paralysis, hypokalaemia induced paralysis should be kept in the differential diagnosis. WHAT IS KNOWN: COVID-19 infection leads to hypokalemia. WHAT IS NEW: Hypokalaemic paralysis as a manifestation of COVID-19.

Glove and instrument changing to prevent bacterial contamination in infected wound debridement and closure procedures: A prospective observational study.

Many surgeons use a single table of instruments for both excisional debridement and coverage/closure of infected wounds. This study investigates the effectiveness of a two-table set-up of sterile instruments, in addition to glove exchange, to reduce instrument cross-contamination during these procedures. This is a prospective, single-site, institutional review board-approved observational study of surgical debridements of infected wounds over a 17-month period. Two separate sterile surgical tables were used for each case: Table A for initial wound debridement (debridement set-up) and Table B for wound coverage/closure (clean set-up). Swabs of each table and its respective instruments were taken after debridement but prior to coverage/closure. The primary outcome of interest was bacterial growth at 48 hours. There were 72 surgical cases included in this study. Culture results of Table A demonstrated bacterial growth in 23 of 72 (32%) cases at 48 hours compared with 5of 72 (7%) from Table B (P = .001). These data suggest that there is significant bacterial contamination of surgical instruments used for debridement of infected wounds. Use of a two-table set-up reduced instrument cross-contamination by 78%, suggesting avoidable re-contamination of the wound.

Building a Multidisciplinary Hospital-Based Wound Care Center: Nuts and Bolts.

BACKGROUND: A hospital-based wound care center provides an important platform for the multidisciplinary approach to wound care. The colocation of specialists is an ideal working environment for the efficient delivery of quality care of the complex wound through daily communication and shared resources. METHODS: We describe the critical components necessary in building a hospital-based wound care center. Furthermore, the experience at the authors' institution in developing the multidisciplinary approach is discussed. RESULTS: Readily available ancillary services, specially trained personnel, continuum of care from the outpatient clinic to admission to surgery, and inpatient and outpatient post operative care all contribute to a process that is especially amenable to the care of the complex wound. CONCLUSIONS: The final goal is to return the patient to the best quality of life achievable given his or her wound or disability. The aim of this study is to present the authors' experiences and provide insight for others who may want to build this model within their institutions.
