Resumo
Background: Anaemia and iron deficiency are common complications following post-bariatric abdominoplasty. Given the low oral absorbability of iron resulting from bariatric surgery, it has been hypothesised that postoperative intravenously administered iron supplementation could be used to treat anaemia and to prevent the development of iron deficiency in these patients. Methods/Design: In this multicentre open-label randomised clinical trial, 56 adult women undergoing post-bariatric anchor-line abdominoplasty will be allocated at a ratio of 1: 1 for postoperative supplementation with two intravenously administered applications of 200 mg of iron saccharate or postoperative supplementation with 100 mg of iron polymaltose complex administered orally, twice a day for 8 weeks. The primary outcome is the difference in mean haemoglobin levels between the two groups at eight postoperative weeks. Secondary outcomes evaluated at one, four and eight postoperative weeks include iron profile, reticulocyte count, overall quality of life measured using the Short-Form 36 Health Survey (SF-36) questionnaire, fatigue measured using the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), adverse effects and postoperative complications. Discussion: This randomised clinical trial aims to evaluate the haematopoietic effectiveness of intravenously administered iron supplementation in patients undergoing post- bariatric abdominoplasty. A more effective recovery of haemoglobin levels could help improve the patients' quality of life and could provide an improved haematological status in preparation for the subsequent and frequent plastic surgeries these patients undergo.
