Elderly patients with heart failure undergoing urgent major surgery suffer substantial cardiac morbidity and mortality. Levosimendan, a novel calcium sensitizer, enhances myocardial contractility while simultaneously having vasodilatory and cardioprotective properties. This could be advantageous in perioperative management of heart failure patients.
Methods
Ten consecutive patients with symptomatic heart failure and left ventricular ejection fraction <35% undergoing urgent hip fracture repair were studied. Levosimendan was administered with an infusion rate of 0.1 μg kg−1 min−1 in a total dose of 12.5 mg starting a minimum of 2 h prior to surgery. Haemodynamic parameters were obtained at baseline and at 4, 8, 12, 16, 20, 24, 28, 36 and 48 h after start of levosimendan. B-type natriuretic peptide was measured on admission and after 48 h.
Results
Patients were 86 ± 7 yr (mean ± SD) of age. Levosimendan significantly increased cardiac index from 2.4 ± 0.3 L min−1 m−2 at baseline to 3.2 ± 0.6 L min−1 m−2 after 24 h by increases in stroke volume index (baseline 27 ± 5 mL m−2, after 24 h 37 ± 10 mL m−2, P < 0.05). Systemic vascular resistance index significantly decreased from 2718 ± 841 to 1964 ± 385 dyn s cm−5 m−2 within 24 h. Haemodynamic changes exerted by levosimendan persisted up to 48 h. B-type natriuretic peptide plasma concentrations decreased from 1143 ± 792 to 935 ± 724 ng L−1 after 48 h (P = 0.006).
Conclusion
In patients with heart failure, preoperative start of levosimendan infusion improves intraoperative and postoperative haemodynamics. These findings suggest that levosimendan is a useful drug for preoperative optimization of cardiac function in high-risk patients undergoing major surgery.
Adequate analgesia is needed after total hip arthroplasty to control pain at rest and during rehabilitation. Our aim was to compare, in a randomized study, the efficacy of two analgesia regimens in control of postoperative pain after total hip arthroplasty: opioid-free continuous psoas compartment block vs. an opioid/non-steroidal anti-inflammatory drugs continuous intravenous infusion.
Methods
In all, 73 patients (ASA I–III), aged 61–82 yr, undergoing total hip arthroplasty were prospectively enrolled in a single-blind randomized trial. Patients were allocated either to the study group (Group A, n = 37) or to the control group (Group B, n = 36). Patients in Group A underwent preoperative placement of a catheter in the psoas compartment and, 30 min before the end of surgery, the catheter was primed with a loading dose of 0.75% ropivacaine (0.4 mL kg−1) followed by a continuous infusion of 10 mL h−1 ropivacaine 0.2% for 48 h. Patients in Group B received, from 1 h before the end of surgery, a continuous intravenous infusion of 0.1% morphine and 0.12% ketorolac at 2 mL h−1 for 48 h. Both groups received spinal anaesthesia for surgery. Pain scores at rest and after mobilization, amount of rescue analgesia, nausea/vomiting and haemodynamic parameters were recorded.
Results
In Group A, median pain scores were very low during the whole study duration both at rest and during physiotherapy in comparison to Group B. Less rescue analgesia was needed and less nausea and vomiting was observed in Group A.
Conclusions
Opioid-free continuous psoas compartment block seems to be an appropriate and reliable technique in providing effective postoperative analgesia at rest and during physiotherapy after total hip arthroplasty when compared to intravenous morphine/ketorolac infusion.
