One-hundred and ninety-two obese patients presented for upper abdominal surgery, of which 110 received general anesthesia with opioid analgesia and 82 patients received general anesthesia with opioid analgesia plus a single-shot intercostal nerve block of 0.5% bupivacaine in 1: 200,000 adrenaline. A significant increase in the time to first post-operative opioid dose and a significant reduction in the number of doses over the first 12 and 24 h periods were noted in the patients receiving intercostal nerve block.

Clinical Trial Controlled Clinical TrialEvaluation of alkalinized lidocaine solution in brachial plexus blockade.
The effect of alkalinization of lidocaine solution in brachial plexus blockade was evaluated in a double blind study. Commercial 1.5% lidocaine with epinephrine 1 : 200,000 (pH 5.72) was compared with an alkalinized solution of lidocaine (pH 7.12). 10 mg.kg(-1) of each solution was administrated by the axillary perivascular technique in 34 adult patients scheduled for elective surgery. The onset and spread of sensory blockade and the intensity of motor blockade were determined. ⋯ Also the analgesic onset in the radial and musculocutaneous nerves was significantly faster than the other two nerves ( P < 0.05 and P < 0.01). Furthermore, the intensity of motor blockade was greatly potentiated when alkalinized lidocaine solution was employed. There was no significant increase in plasma concentration of lidocaine in patients who were given alkalinized solution.

We compared two methods of respiratory managements during bronchoplasty surgery. In one lung ventilation group (OLV-G), 10 patients were ventilated with Broncho-cath tube or Univent tube. On another 10 patients, ventilation was performed with Univent tube following insertion of bronchial blocker into main bronchus of dependent lung. ⋯ Oxygenation index (O. I.) of S-HFJV-G was significantly higher than that of OLV-G when bronchus was open. These phenomena might have occurred through prevention of pulmonary blood flow shift to the non-dependent lung when S-HFJV was used.
