Prophylactic phenylephrine infusion for the prevention of hypotension after spinal anesthesia in the elderly: a randomized controlled clinical trial.

Study Objective: Hypotension frequently occurs during spinal anesthesia (SA), especially in the elderly. Phenylephrine is effective to prevent SA-induced hypotension during cesarean delivery. The objective of this study was to evaluate the efficacy and safety of prophylactic infusion of phenylephrine after SA for orthopedic surgery in the elderly.

Preoperative use of epoietin beta in total hip replacement: a prospective study.

Objective: Epoietin (EPO) effectively decreases perioperative blood transfusion requirements. We evaluated the feasibility of using EPO beta to increase haemoglobin levels before total hip replacement (THR) and reduce transfusion.

Materials And Methods: One hundred and seventy-one patients undergoing primary THR were included in this prospective observational study.

Postoperative analgesia after total hip arthroplasty: patient-controlled analgesia versus transdermal fentanyl patch.

Study Objective: To determine whether a new transdermal fentanyl patch (TFP) is a good choice for the postoperative pain management of patients undergoing primary total hip arthroplasty compared with patient-controlled analgesia (PCA).

Design: Randomized, prospective study.

Setting: University hospital.

The optimal motor response for infraclavicular brachial plexus block.

Background: In this prospective study we compared the success of the infraclavicular brachial plexus block using double-stimulation in regard to the second nerve response elicited with neurostimulation.

Methods: Six-hundred-twenty-eight patients undergoing emergency upper limb surgery using infraclavicular brachial plexus block were included in this study. The musculocutaneous nerve was initially blocked and the groups were then evaluated according to the second nerve located, which was radial in 54%, median in 35%, and ulnar in 11% of patients.

Infraclavicular brachial plexus block versus humeral approach: comparison of anesthetic time and efficacy.

Unlabelled: Most upper arm regional anesthesia techniques are successful and differences in efficacy should not dictate the choice of technique. In the present study, we compared humeral block (HB) and infraclavicular brachial plexus block (ICB) using anesthetic time (i.e.

Resident versus staff anesthesiologist performance: coracoid approach to infraclavicular brachial plexus blocks using a double-stimulation technique.

Objectives: Infraclavicular brachial plexus block with double stimulation (ICB) is a safe technique for upper-limb anesthesia. However, the experience of learning this technique by anesthesiology residents has not been reported. The aim of this study was to compare staff with resident anesthesiologists in the performance of ICB.

[Neurostimulation does not increase the success rate of saphenous nerve blocks].

Purpose: To evaluate neurostimulation of motor components of the vastus medialis muscle and the rectus femoris muscle, with a view to blocking the medial sensory fibres of the saphenous nerve.

Method: First we dissected four femoral trigones, in order to select our puncture point. We were able to observe that, at the flexion crease of the thigh, the different fibers that make up the femoral nerve were clustered together and the saphenous nerve and the vastus medialis nerve had not yet separated from the femoral stem.

A modified coracoid approach to infraclavicular brachial plexus blocks using a double-stimulation technique in 300 patients.

Infraclavicular brachial plexus block is used less than other techniques of regional anesthesia for upper-limb surgery. We describe a modified coracoid approach to the infraclavicular brachial plexus using a double-stimulation technique and assess its efficacy. Patients undergoing orthopedic surgery of the upper limb were included in this prospective study.
