Scalpel Versus Diathermy for Transverse Abdominal Incision in Women Undergoing First Elective Caesarean Section: a Randomized Controlled Trial

The objective of this study will be to compare two methods of skin incisions during the first caesarean section (CS), that is scalpel and diathermy, assessing differences in blood loss during incision, incisional time, total surgery time, post-operative pain, wound healing, complications, and cosmetic outcomes.

Study Overview

Detailed Description

The scalpel has been historically used as the primary cutting tool during caesarean section (CS). However, advancements in surgical devices have introduced alternatives, such as the option to make a diathermic cut using electrosurgical units.

General surgeons have extensively demonstrated the advantages of diathermy over the scalpel for abdominal wall incisions, including faster opening time, reduced incisional blood loss, decreased post-operative pain, and a comparable wound complication rate.

In obstetrics, there is a scarcity of evidence in this regard, and no consensus or guidelines have been established regarding the optimal method for making a transverse abdominal incision during the first elective CS. Currently, the choice between using a scalpel or diathermy remains at discretion of the obstetric surgeon. The objective of this study will be to compare both methods of skin incisions during the first CS, assessing differences in blood loss during incision, incisional time, total surgery time, post-operative pain, wound healing, complications, and cosmetic outcomes.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Group_A: skin incision with scalpel.
In the scalpel group, the skin incision will be made using the traditional method, with a scalpel (No. 22).

A Pfannenstiel skin incision will be performed using a scalpel, extending through the subcutaneous tissue and rectus sheath. After separation of rectus muscles, peritoneum will be visualized and opened. Optimal hemostasis will be achieved by applying pressure to skin blood vessels and ligating any subcutaneous bleeding.

Group A: skin incision with a scalpel.

Active Comparator: Group_B: skin incision with diathermy.
In the diathermy group, the incision will be made using a small flat blade pen electrode without applying pressure. The electrode will be set to cutting mode, delivering a sinusoidal current of maximum 120 watts.

A Pfannenstiel skin incision will be made using a scalpel. Subsequently, a diathermy pen electrode will be employed for the dissection of deeper tissues.

Optimal hemostasis will be achieved by using the same blade pen electrode, set to coagulation mode.

Group B: skin incision with diathermy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incision blood loss
Time Frame: During surgery
This will be calculated by weighing the gauze pre and postoperatively (1mg = 1ml) after complete hemostasis will be achieved.
During surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incision time
Time Frame: During surgery
We will compare incisional time by using a digital clock. The incisional time will be established as follows: when skin incision will be made, the surgeon will verbally announce "start ". Once the parietal peritoneum will be opened, the surgeon will announce "stop". The incision time will be calculated as the difference between "start" and "stop" times.
During surgery
Total surgery time
Time Frame: During surgery
Total surgery time will be the time between the start of the skin incision and the completion of the skin suture.
During surgery
Wound complications
Time Frame: During the first month after surgery
Will include edema, seroma, hematoma, dehiscence, and infection. The wound will be evaluated 24h and 72h after surgery, before patients discharge. Then, outpatient wound evaluation will be made 7 and 30 days after surgery.
During the first month after surgery
Post-operative pain assessed by VAS
Time Frame: During the first three days after surgery
Post-operative pain will be evaluated for each participant at 1, 4, 8, 16, 24, 48, 72 hours postoperatively, by using the Visual Analog Scale (VAS). The VAS consists of a 10 cm long horizontal line with its extremes marked as 'no pain' (0) and 'worst pain imaginable' (10).
During the first three days after surgery
Cosmetic wound evaluation assessed by POSAS
Time Frame: One month after surgery
The cosmetic aspect of the wound will be evaluated outpatient 30 days after surgery by using the Patient and Observer Scar Assessment Scale (POSAS), that is a questionnaire that was developed to assess scar quality. It consists of two separate six-item scales (Observer Scale and Patient Scale), both of which are scored on a 10-point rating scale (1 = best result; 10 = worst result).
One month after surgery
