Comparative induction of controlled circulation by magnesium and remifentanil in spine surgery

AIM: To evaluate the efficacy of magnesium sulfate(MGS) in comparison with remifentanil for induction of relative hypotension in posterior fusion of spine(PSF).METHODS: In this randomized clinical trial, 40 patients with the American Society of Anesthesiologists Ⅰ and Ⅱ physical status undergoing lumbar PSF were randomized to receive remifentanil(REM) 0.15 μg/kg or MGS 50 mg/kg for controlled hypotension. The administering anesthesiologist was blinded to the medication. Continuous infusion was maintained at a fixed volume rate to deliver precalculated doses of either study drugs. All other aspects of anesthesia and surgery were similar in the two groups. The target mean arterial pressure(MAP) range used in this study was 60-70 mm Hg. In the course of surgery, the hemodynamic variables, volumeof blood loss, urine output, fluid intake and surgeon's satisfaction were recorded. Data was analyzed with SPSS version 13.0 and P values less than 0.05 were considered significant.RESULTS: Twenty patients in the MGS group and 19 patients in the REM group were studied. There was no difference between the two groups in the hemodynamic variables, blood loss, urine output, fluid requirement and surgeon's satisfaction for exposure. The target MAP was achieved in 75% of Mg and 58% of remifentanil groups. Although a higher number of patients in the REM group required nitroglycerin(42.1%) to reach the target MAP than those in the MGS group(25%), this difference was not statistically significant(P = 0.32).CONCLUSION: Our findings showed that in patients undergoing lumbar PSF surgery, remifentanil and MGS have a similar hypotensive effect and comparable amount of blood loss without any significant adverse effects.     

Dexmedetomidine as a hypotensive agent: Efficacy and hemodynamic response during spinal surgery for idiopathic scoliosis in adolescents

BackgroundThis study was designed to evaluate the efficacy of dexmedetomidine as a hypotensive agent in comparison to sodium nitroprusside in scoliosis surgery.MethodForty patients ASA I or II aged (12–16) year scheduled for scoliosis surgery were randomly assigned to receive either dexmedetomidine 1 μg/kg over 10 min before induction of anesthesia followed by 0.2–0.5 μg/kg/h infusion during maintenance (DEX group) or sodium nitroprusside 1–10 μg/kg/min infusion after induction of anesthesia (SNP group) to maintain mean arterial blood pressure between (60–65 mmHg). Mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), systemic vascular resistance index (SVRI) and stroke index (SI) were recorded. The two groups were compared with reference to reversibility of hypotensive state, intraoperative blood loss and transfusion requirement.ResultsDexmedetomidine administration resulted in significant reduction in MAP, HR and CI. During the steady state hypotension SNP group showed significant increase in HR and CI compared to baseline and to DEX group (P < 0.05). SVRI was significantly lower during controlled hypotension in SNP group compared to DEX group (P < 0.001). Time to restoration of baseline MAP was longer with DEX group (10.21 ± 1.52 min) than SNP group (4.87 ± 0.86 min) (P < 0.001). Blood loss and transfusion requirement were significantly lower in DEX group than SNP group [1095.62 ± 128.9 6 ml versus 1287.50 ± 182.54 ml, P = 0.0013] and [855.42 ± 140.23 versus 1006.00 ± 154.66 ml, P = 0.0026], respectively.ConclusionDexmedetomidine is a safe and effective drug for controlled hypotension in scoliosis surgery. It may offer the significant advantage of reducing blood loss and transfusion requirement.

The effect of milrinone on induced hypotension in elderly patients during spinal surgery: a randomized controlled trial

Background contextInduced hypotension is widely used intraoperatively to reduce blood loss and to improve the surgical field during spinal surgery.PurposeTo determine the effect of milrinone on induced hypotension during spinal surgery in elderly patients.Study design/settingProspective randomized clinical trial.Patient sampleForty patients, 60 to 70 years old, ASA I–II, who underwent elective lumbar fusion surgery.Outcome measuresIntraoperative hemodynamics, blood loss, hourly urine output, and grade of surgical field.MethodsAll patients were randomized to group M or N. The study drug was infused after perivertebral muscle retraction until complete interbody fusion. In group M, 50 μg/kg/min of milrinone was infused over 10 minutes as a loading dose followed by 0.6 μg/kg/min of milrinone as a continuous dose. In group N, an identical volume of normal saline was infused in the same fashion. This study was not funded by commercial or other sponsorship and the authors confirm no conflicts of interest, financial or otherwise.ResultsDuring infusion of the study drug, the systolic and mean blood pressures were maintained within adequate limits of induced hypotension in group M. Intraoperative blood loss was 445.0±226.5 mL in group M and 765.0±339.2 mL in group N (p=.001). Hourly urine output was 1.4±0.6 mL in group M and 0.8±0.2 mL in group N (p<.001). The grade of the surgical field was better in group M than in group N (p=.004).ConclusionsWe conclude that milrinone is useful for induced hypotension in elderly patients during spinal surgery.     

Sevoflurane for controlled hypotension during spinal surgery: preliminary experience in five adolescents

The physical properties of sevoflurane suggest that it may be a suitable agent for controlled hypotension. With its low blood:gas partition coefficient of 0.69, it has a rapid onset of action making it easy to rapidly control blood pressure. The current report outlines preliminary experience with sevoflurane for controlled hypotension during posterior spinal fusion in five adolescents. The patients ranged in age from 12 to 16 years and in weight from 49 to to 72 kg. The duration of controlled hypotension varied from two to three h. The expired sevoflurane concentration required to maintain the mean arterial pressure (MAP) at 55 to 65 mmHg varied from 2 to 4%. With sevoflurane, there was an increase in heart rate from baseline of 74±7 beats·min^?1 to a maximum of 83±13 beats·min^?1 (P=0.038). One patient required three intravenous doses of esmolol (10 mg each) for a heart rate in excess of 100 beats·min^?1. Estimated blood loss varied from 300 to 850 ml. No patient received homologous blood. No excessive hypotension was noted with sevoflurane. No patient required calcium, alpha adrenergic agonists, or ephedrine for excessive hypotension. When controlled hypotension was no longer necessary, the sevoflurane concentration was decreased to 1%. After decreasing the sevoflurane to 1%, the time to return of the MAP to baseline varied from 4 to 8 min (5.6±1.8 min).
