[Propofol to facilitate spinal anesthesia in the lateral position in patients with femoral neck fracture].

PURPOSE: The aim of this study was to assess the feasibility and efficacy of propofol before positioning elderly patients with a femoral neck fracture in the lateral decubitus position, to perform a spinal anesthetic. METHODS: In this prospective and descriptive study, 79 consecutive patients, > 75 yr old, with a femoral neck fracture were included. Propofol, 0.5 mg x kg(-1), was administered. If loss of consciousness was not obtained (Ramsay score < or = 3/6), then additional doses of 0.25 mg x kg(-1) were given until a Ramsay score of 4 or 5 was attained. Then, the patient was turned to the lateral decubitus position, the fractured side up. The efficacy of propofol was assessed by observing a grimace during positioning and asking the patients if they had recall of pain. Hemodynamic data and oxygen saturation were collected. RESULTS: Forty-three patients required a single injection, 34 required two injections and only two patients required three injections. No grimace and no recall of pain were recorded during the study. There was no desaturation (SpO(2) < 92 %), and hypotension, defined as a systolic blood pressure decrease > 30% from baseline, was observed. CONCLUSION: Propofol is a simple and efficacious means of providing comfort while positioning elderly patients with a femoral head fracture before performing spinal anesthesia.

Spinal anesthesia using single injection small-dose bupivacaine versus continuous catheter injection techniques for surgical repair of hip fracture in elderly patients.

Aging and disease may make elderly patients particularly susceptible to hypotension during spinal anesthesia. We compared the hemodynamic effect of continuous spinal anesthesia (CSA) and small dose single injection spinal anesthesia (SA) regarding the incidence of hypotension. Seventy-four patients aged >75 yr undergoing surgical repair of hip fracture were randomized into 2 groups of 37 patients each. Group CSA received a continuous spinal anesthetic with a titration of 2.5 mg boluses every 15 min of isobaric bupivacaine, while group SA received a single injection spinal anesthetic with 7.5 mg of isobaric bupivacaine. The overall variations in noninvasive automated arterial blood pressure were not statistically significantly different in the 2 groups at baseline and after CSA or SA (not significant). In the SA group, 68% of patients experienced at least one episode of hypotension (decrease in systolic arterial blood pressure greater than 20% of baseline value) versus 31% of patients in the CSA group (P = 0.005). In the SA group, 51% of patients experienced at least one episode of severe hypotension (decrease in systolic arterial blood pressure more than 30% of baseline value) versus 8% of patients in the CSA group (P < 0.0001). In the CSA group, 4.5 +/- 2 mg of ephedrine was injected versus 11 +/- 2 mg in the SA group (P = 0.005). In the CSA group, 5 mg (2.5-10) of anesthetic solution was required versus 7.5 mg in the SA group (P < 0.0001). We conclude that, in elderly patients undergoing hip fracture repair, CSA provides fewer episodes of hypotension and severe hypotension compared with a single intrathecal injection of 7.5 mg bupivacaine.
