Abstract
Dry and wet techniques were used in the past during liposuction but associated with more blood loss so tumescent and superwet techniques are used nowadays because they have less blood loss about 1% of total aspirated volume. There are different methods for liposuction but suction assisted liposuction is the most common used technique. Large volume liposuction associated with more complications that may occur such as volume overload, pulmonary edema, anemia, visceral injury, thromboembolism, and local anesthetic systemic toxicity. It can be performed under general, local or regional anesthesia. Fluid management especially in large volume liposuction remains a challenge. Many formulae and theories were used seeking the ideal fluid management of large volume liposuction. Some used the intraoperative fluid, others used residual volume theory, invasive and non-invasive techniques. Electrical cardiometry (EC) is FDA approved non or minimally invasive device that can be used for assessment of fluid status in large volume liposuction through measurement of various hemodynamic parameters such as cardiac output, stroke volume, stroke volume variation (SVV) and corrected flow time. SVV can be used for fluid responsiveness and assessment of volume status of the patient. The aim of our study was to compare the hemodynamic parameters of fluid resuscitation using Rohrich formula versus cardiometry guided stroke volume variation in patients undergoing large volume liposuction surgery. The primary outcome was the mean arterial blood pressure at 4 aspirated litres and at every aspirated litre after. The secondary outcomes were blood loss assessment, urine output measurement and total fluid measurement. This prospective randomized single blinded study was carried out in Tanta University Hospitals on 50 patients who were randomly allocated into two groups (25 in each). group A, IV fluids managed by Rohrich formula through the intraoperative fluid which was 1.2. group B, IV fluids managed by EC guided SVV, fluid bolus of lactated ringer (4 ml /kg over 15 min) was administered when SVV ˃ 15% and fluid maintenance of 2 ml/kg/h was infused in both groups. The main results of our study were as following: Demographic data, duration of surgery, SPO2, HR, MAP, total aspirate, total fat, infranatant fluid, total infiltrate, Hb in aspirate, venous Hb & Hct and blood volume in aspirate were comparable between the two studied groups with p value ˃ 0.05 (statistically insignificant). UOP and total IV fluids were significantly higher in group A (Rohrich Formula) than group B (EC). Two patients received blood transfusion in each group. No complications like pulmonary edema, pulmonary embolism, DVT, LAST or congestive heart failure occurred.
