To compare harmonic scalpel with electrocautery for outcomes i.e. estimated blood loss (EBL), operating time, drain Volume and drain Days, seroma formation, surgical site infection and postoperative pain in adult females undergoing MRM at a tertiary care hospital. We hypothesized that harmonic yields better outcome than electrocautery dissection.

Condition Intervention Phase
Breast Cancer Modified Radical Mastectomy Device: Harmonic Procedure: electrocautery Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized

Primary Outcome Measures:
  • Duration of drains (days) [ Time Frame: 30 days ]
    Durations of drains in place after MRM: Patients were followed in clinic every 3rd day and drains were removed once the volume was <30ml a day.

Secondary Outcome Measures:
  • Operative time [ Time Frame: 3-4 hours ]
    Time taken in minutes from incision to skin closure

  • Drain Volume [ Time Frame: 30 days ]
    Daily charting of drain volume at a specified time with regular recording in routine clinic follow ups till the drains were is place.

  • Overall complications [ Time Frame: 30 days ]

    Patients were followed up till 3o days. If any of the following were found, the patient was labelled to have complication:

    Seroma- fluctuant swelling under the flaps; SSI- as per CDC criteria; Hematoma- swelling under flaps with characteristic bruising; Flap necrosis- partial or complete necrosis of flaps.

  • Pain [ Time Frame: 24 hours ]
    Pain was measured by Visual Analogue score (1-10) by a registered nurse at 24 hours

Enrollment: 152
Study Start Date: March 2010
Study Completion Date: August 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Electrocautery
Raising of the flaps with electrocautery
Procedure: electrocautery
Dissection in modified radical mastectomy
Experimental: Harmonic
Dissection with harmonic scalpel in modified radical mastectomy
Device: Harmonic
Dissection with harmonic scalpel

Detailed Description:
In this randomized controlled trial, adult females who underwent MRM between April 2010 and July 2011 were randomized to receive either intervention A (harmonic scalpel) or B (electrocautery). The procedure was standardized except elevation of flaps and axillary dissection, that was performed as per randomization. Patients were followed up in clinic for four weeks. The outcomes were estimated blood loss (EBL), operating time, drain Volume and drain Days, complications (seroma, surgical site infection, hematoma and flap necrosis) and postoperative pain.
