Randomized Controlled Trial Comparative Study Clinical Trial
Effect of intercostal nerve blockade during operation on lung function and the relief of pain following thoracotomy.
The use, during operation, of intercostal nerve blocks with lignocaine and bupivacaine for the relief of pain following thoracotomy was assessed in 138 patients. Irrespective of the method used to evaluate efficacy, it was not possible to demonstrate a lasting effect of clinical significance favouring either local anaesthetic agent. This form of treatment, although free from serious side effects, had no beneficial effects on lung function and is not recommended for the relief of pain following surgery.

Axillary nerve block is a safe and reliable method of providing anesthesia for the upper extremity. It is particularly useful because it can be applied in cases of traumatic injury where general anesthesia might present particular hazards. The use of a large volume of anesthetic solution is important, particularly when it is essential to block the musculocutaneous or axillary nerve.

Effect of regional analgesia on maternal oxygen consumption during the first stage of labor.
Oxygen consumption, tidal volume, and minute volume decreased in 20 patients during the first stage of labor after either epidural or paracervical block. The elimination of pain with optimum regional analgesia is associated with a decrease in tidal and minute volumes, apprehension, and consequently a decreased oxygen consumption. These factors may contribute to a decrease in maternal lactic acidosis during labor.
