Nurse-managed basal-bolus versus sliding-scale insulin regimen in subjects with hyperglycemia at admission for orthopedic surgery: a propensity score approach.

AIMS: A sliding-scale (SS) regimen is discouraged to correct hyperglycemia in hospital patients, but there is resistance to adoption of basal-bolus (BB) treatment in surgical units. We tested the feasibility and the effects of a nurse-based BB regimen in orthopedic surgery. METHODS: Following an intense training to implement a protocol amenable by nurses, a group of patients admitted with hyperglycemia in an orthopedic institute were prospectively followed according to a basal-bolus insulin regimen (BB, n = 80). They were compared with a hyperglycemic group eventually treated by sliding-scale insulin on demand (SS, n = 122). Diabetes was present in 196 cases. Metabolic control was assessed during the first 3 days of surgery; outcome data were tested by logistic regression, after adjusting for propensity score. RESULT: Average blood glucose and glucose variability were lower in BB versus SS (P < 0.001), in the presence of similar 3-day insulin doses. Complications were recorded in 68 cases (16.2% vs. 45.1% in BB and SS, respectively). BB regimen was associated with propensity-adjusted reduction in all adverse events [odds ratio (OR) 0.36; 95% confidence interval (CI) 0.17-0.76] and of systemic infections (OR 0.18; 95% CI 0.07-0.50) and with shorter hospital stay (8.8 ± SD 5.2 days vs. 12.5 ± 7.4; P < 0.01). The superiority of BB regimen was confirmed in the pair-matched analysis. CONCLUSIONS: The study proves the feasibility and the superiority of nurse-based BB versus SS treatment in metabolic control and on the risk of adverse events in orthopedic surgery patients with hyperglycemia.

Liver and skeletal muscle injury in a 12-year-old female patient after scoliosis correction in prone position: a case report.

We report the case of a 12-year-old female, otherwise healthy patient, who underwent surgery for scoliosis correction in prone position under total intravenous general anesthesia, with CardioQ and sensory-motor-evoked potentials for hemodynamic and neurological monitoring. The patient showed severe intraoperative hypotension, lactic acidosis, and complete abolition of motor-evoked potentials during the positioning of posterior corrective bars. During the postoperative period, the increase in muscle and liver enzymes indicated an abdominal organ damage and confirmed hypoperfusion of the lower limbs. Both side effects were caused by the malposition of the patient on the operating table. The case resolved within the first postoperative week without sequelae.
