    Volume Replacement Therapy during Hip Arthroplasty using Hydroxyethyl Starch (130/0.4) Compared to Lactated Ringer Decreases Allogeneic Blood Transfusion and Postoperative Infection
    (2013) HAMAJI, Adilson; HAJJAR, Ludhmila; CAIERO, Marcelo; ALMEIDA, Juliano; NAKAMURA, Rosana Ely; OSAWA, Eduardo A.; FUKUSHIMA, Julia; GALAS, Filomena R.; AULER JUNIOR, Jose Otavio Costa
    Background and objectives: Hydroxyethyl starch (HES) 130/0.4 is considered an effective plasma expander when compared to crystalloids. There is controversy around its superiority regarding hemodynamic optimization and about possible detrimental effects on coagulation. The aim of this study was to compare the effects of HES 130/0.4 to lactated Ringer solution during hip arthroplasty in adult patients under spinal anesthesia regarding intraoperative bleeding, hemodynamic parameters, coagulation profile, transfusion requirements and clinical outcomes. Methods: In this randomized, controlled trial, 48 patients scheduled for hip arthroplasty with spinal anesthesia were randomized into two groups: 24 patients were allocated to receive a preload of 15 mL.kg(-1) of HES 130/0.4 and 24 patients received a preload of 30 mL.kg(-1) lactated Ringer solution before surgery. Hemodynamic measurements, hemoglobin concentrations, biochemical parameters and coagulation tests were evaluated in three periods during surgical procedure. Patients received medical follow-up during their hospital stay and up to postoperative 30 days. Primary outcome was the requirement of red blood cell transfusion between groups during hospital stay. Secondary outcome were hemodynamic parameters, length of hospital stay, mortality and occurrence of clinical postoperative complications. Results: Red blood cell transfusion was required in 17% of patients in the HES group and in 46% in the Ringer group (p = .029). Postoperative infections were more frequently observed in the Ringer group (17%) compared to the HES group (0), p = .037. There were no significant differences between groups in mortality, hospital length of stay and clinical complications other than infection. Conclusions: During hip arthroplasty, patients treated with hypervolemic hemodilution with hydroxyethyl starch 130/0.4 required less transfusion and presented lower infection rate compared to patients who received lactated Ringer.

    Comparative Study Related to Cardiovascular Safety between Bupivacaine (S75-R25) and Ropivacaine in Brachial Plexus Block
    (2013) HAMAJI, Adilson; REZENDE, Marcelo Rosa de; MATTAR JR., Rames; VIEIRA, Joaquim Edson; AULER JR., Jose Otavio Costa
    Background and objectives: Bupivacaine is a first choice for regional anesthesia considering its effectiveness, long duration and less motor blockade. Bupivacaine (S75-R25) is a mixture of optical isomers containing 75% levobupivacaine (S-) and 25% dextrobupivacaine (R+) created by a Brazilian pharmaceutical company. This investigation compared cardiac safety and efficacy of bupivacaine S75-R25 with vasoconstrictor and ropivacaine for brachial plexus blockade. Methods: Patients were randomized to receive brachial plexus anesthesia with either bupivacaine S75-R25 with epinephrine 1:200,000 (bupi) or ropivacaine (ropi), both at 0.50%, in 30 mL solution. We registered a continuous Hotter ECG throughout the procedure, as well as the Lovett scale of force in addition to monitoring (heart rate, pulse oximetry and non-invasive blood pressure). The incidence of adverse events was compared with the chi-square or Fisher test. Results: We allocated forty-four patients into two groups. They did not show any difference related to age, weight or height, gender, as well as for surgical duration. Supraventricular arrhythmias were not different before or after the plexus blockade, independent of the local anesthetic chosen. Loss of sensitivity was faster for the bupivacaine group (23.1 +/- 11.7 min) compared to the ropivacaine one (26.8 +/- 11.5 min), though not significant (p = 0.205, Student t). There was a reduction in the cardiac rate, observed during the twenty-four-hour Hotter monitoring. Conclusions: This study showed similar efficacy between bupivacaine S75-R25 for brachial plexus blockade and ropivacaine, with similar incidences of supraventricular arrhythmias.
