Abstract
Burn wound debridement is an important step in management of major burns. There are several techniques of burn wound debridement include surgical, enzymatic, mechanical and autolytic. Hydrosurgical system is an additional type of debridement that preserve viable tissues, create smooth wound bed and decrease bacterial load.
This study is a prospective and comparative that compared traditional surgical debridement versus hydrosurgical debridement of major burns. This study was conducted between December 2020 to December 2021 at 2 major burn centers in Egypt (Burn unit of Ain Shams University hospital and Armed Forces Burn Center at El Helmia Armed Forces Hospital).
Twenty patients with mixed depth of major burns were divided into two groups. In group I (n=10) debridement done surgically by Watson knife. In group II (n=10) debridement done by hydrosurgical system.
In this study, adults of both sex (18-45) years were included. Also, the study includes mixed pattern burn with total body surface area (TBSA) (20-30%) of any burn etiology.
Patients less than 18 years and more than 45 years were not included in the study. TBSA less than 20% or more than 30 were also excluded. Also, we exclude patients with comorbid disease.
Both groups were compared regarding intraoperative blood loos, blood component transfusion, mean number of sessions, mean duration of each session, healing time, risk of infection.
As regard protocol of burn centers that study take place in, debridement not exceed 10% per session and also early excision was followed at 48h after burn injury. In both group, debridement occurred under general anesthesia.
The number of sessions that each patient need was measured in both groups. The following parameters were calculated in each session and compared in the two groups; type of intervention (either excision only or excision plus STSG), Mean Hb (gm/dl), Duration of each session (min.), estimated blood loss (mL), blood component transfusion, and vital data.
All surgical interventions were documented and analyzed regarding mean post operation HB, blood component transfusion. Wound bed was followed up especially for signs of improvement and infection.
Healing time of each patient was measured in days and documented. Scar quality was noticed and compared between both groups using Vancover scar scale.
This study showed that, mean number of sessions, the estimated blood loss, healing time, blood component transfusion and risk of infection were lower in hydrosurgical debridement than traditional surgical debridement group.
