Pain After Tumescent Mastectomy or Standard Mastectomy in Women With Stage I, Stage II, or Stage III Breast Cancer

2017年6月19日 更新者:University of California, Davis

Tumescent Mastectomy: A Prospective Comparison to Standard Mastectomy Technique

RATIONALE: New surgery techniques may lessen pain after breast surgery. It is not yet known whether tumescent mastectomy or standard mastectomy results in less pain in women with breast cancer.

PURPOSE: This clinical trial is studying pain after tumescent mastectomy compared with pain after standard mastectomy in women with stage I, stage II, or stage III breast cancer.

研究概览

详细说明

OBJECTIVES:

Primary

  • To compare post-operative pain after tumescent vs standard mastectomy in women with stage I-III breast cancer.

Secondary

  • To compare the total time of operation from incision to completion of wound closure.
  • To compare the time of operation from first incision to completion of skin flaps.
  • To compare the total estimated blood loss.
  • To compare the number of days the Jackson-Pratt drain is left in place under skin flaps with wound drainage > 30 mL/24 hours.
  • To compare the incidence of wound complications such as skin necrosis, hematoma, cellulitis, abscess, and seroma between groups.

OUTLINE: Patients are grouped according to which surgeon provided their evaluation and treatment recommendations.

  • Group 1: Patients undergo standard mastectomy.
  • Group 2: Patients undergo tumescent mastectomy. All patients receive standardized post-operative pain management comprising morphine sulfate for analgesia or an equivalent dose of hydromorphone hydrochloride for 24 hours following surgery. Patients then receive 1-2 oral acetaminophen/oxycodone hydrochloride combination tablets (or a comparable amount of another narcotic/acetaminophen combination) every 6 hours as needed. Pain is assessed using the Short-form McGill Pain Questionnaire (SF-MPQ).
