RESUMO
Surgical scalpels are traditionally used for skin incisions during a Caesarean delivery; the great evolutions in electrosurgical devices bring an alternative method for skin incision by the usage of cutting diathermy. This was a prospective randomised comparative study conducted during the period from March 2016 to February 2017 on 200 patients, 100 patients had skin incisions using the surgical scalpel, while 100 patients had skin incisions with a diathermy, in order to judge the variations in the postoperative pain, the incision time, the incision blood loss, the operative time, the wound healing and the wound complications. We observed a significant difference between the two groups regarding the incision time (p < .001), incisional blood loss (p < .001), operative time (p < .001) and the postoperative pain (p < .001), where these parameters were less in the diathermy group. No significant difference observed between the two groups regarding the wound healing (p = .389) and wound complications (p = .470). We can conclude that the proper usage of diathermy in making the skin incision during a Caesarean section in this study achieved better results than the scalpel incision. Impact statement What is already known on this subject? Surgical scalpels are traditionally used in making the skin incisions during a Caesarean section; diathermy incisions, on the contrary, are less popular among the surgeons. It has been hypothesised that the application of extreme heat may result in a significant postoperative pain and poor wound healing. There has been a widespread use of diathermy for hemostasis but fear of production of large scars and improper tissue healing has restricted their usage in making skin incisions. What do the results of this study add? The use of diathermy for skin incisions in Caesarean section in this study was associated with a reduced incisional blood loss, incisional time, operative time and postoperative pain. It had no effect on wound closure and was not associated with any delay in wound healing. Also, the wound complications rate was equal in both types of incisions. What are the implications of these findings for clinical practice and/or further research? Most surgeons prefer the scalpel in making skin incision during a Caesarean section due to the fear of surgical site infection. Our findings proved different, we proved that cutting diathermy could be accepted as an alternative technique for making a skin incision without increased rates of wound infections. Also, the advantages of cutting diathermy will give benefits to both the patients and the surgeons.
