title: Comparison of postoperative pain in diathermy and conventional scalpel Skin incision after mastectomy in Ibadan, Nigeria.
abstract: BACKGROUND
  Pain control is a challenge after surgery. Inadequate control of acute postoperative pain in mastectomy patients may lead to chronic post mastectomy pain syndrome. The study aimed to compare the effect of diathermy incision with scalpel incision on the severity of acute postoperative pain after mastectomy.
  
  
  METHODS
  Sixty three females had mastectomy under general anaesthesia. Thirty two patients had skin incisions made with scalpel while 31 patients with diathermy. Both groups received intraoperative Fentanyl and Tramadol. Tramadol was also employed as postoperative analgesic while Paracetamol was given as the rescue analgesic. The outcome measures were pain scores using visual analogue score (VAS) and analgesic consumption within the twenty four hours postoperatively.
  
  
  RESULTS
  The mean VAS in the diathermy group versus scalpel group at 6th, 12, 18th and 24th hour post operatively were 11.84 +/- 6.15 mm versus 16.18 +/- 8.5 mm (p=0.001), 11.10 +/- 4.26 mm versus 15.84 +/- 5.12 mm (p=0.001), 11.07 +/- 4.15 mm versus 17.32 +/- 6.01 mm (p=0.001), 10.6 +/- 8.08 mm versus 19.19 +/- 8.7 mm (p = 0.001) respectively. The mean dose of Tramadol was 264 +/- 84 mg in the diathermy group versus 278 +/- 64 mg in the scalpel group p=0.189, three patients required rescue analgesic (paracetamol) in the diathermy group mean dose 1.5.7 +/- 0.54 g versus 7 patients in the scalpel group, mean dose 1.67 +/- 0.58 g p=0.75.
  
  
  CONCLUSIONS
  Diathermy can contribute to reduction in the acute postoperative pain in patients undergoing mastectomy.
