[The perineural administration of opiates during regional conduction block of nerve trunks and plexuses]

The effect of perineural administration of narcotic analgesics on the efficacy of nerve trunk and plexus blockade has been studied in 290 patients with traumas and surgical diseases. It has been established that combined administration of a local anesthetic and narcotic analgesic into a brachial fascia and sciatic nerve ensures a more even, adequate and durable analgesia during and after surgery on the upper and lower extremities. Similarly, the results of paravertebral analgesia after abdominal surgery are improved. It is also concluded that thermographic registration of infrared irradiation intensity in a "pain" dermatome zone gives an objective information on the efficacy and duration of postoperative analgesia.
