Outcomes of Craniotomy Scalp Incision Using Cutting Micro-Needle Diathermy versus Traditional Stainless-Steel Scalpel.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Scalp incision bleeds profusely due to its high vascularity. In other regions of the body, studies have debunked the initial concern of poor wound outcomes thought to be associated with thermal skin injury if diathermy is used to make skin incision and found that skin incision with diathermy led to reduced incisional blood loss. Studies on cranial operations involving scalp incisions in which incisional blood loss is more likely are scarce. Objective: The objective of this study was to compare the outcomes of scalp incisions using either cutting micro-needle diathermy (MND) or the traditional stainless-steel scalpel (TSSS) during craniotomy. Materials and Methods: The study was a hospital-based, prospective, randomized comparative study. Consented adult patients who had craniotomy were randomized into either cutting MND or TSSS group. Outcome measures were volume of blood loss per wound length and incision duration per wound length during scalp incision, 30-day surgical site infection (SSI), and scar appearance at 3 months postoperatively. Statistical Analysis: The data were analyzed using SPSS version 23, and statistical significance was set at Results: A total of 56 patients were recruited for the study, with 28 patients in each group. The mean age of the patients was 36.21 ± 13.90 years. The mean volume of incisional blood loss per wound length was 3.21 ± 2.06 and 4.65 ± 3.25 mL/cm in MND and TSSS groups, respectively ( Conclusion: The study revealed no significant difference in the outcomes of craniotomy scalp incision between the two methods of making scalp incision. The study concludes that the use of diathermy in making scalp incision is not inferior to the use of the traditional scalpel, and the method of scalp incision may be left to the discretion of the surgeon.
