Probably the most common procedure in dentistry is the administration of local anesthetic, or LA. Immediate complications of LA administration include positive blood aspiration, blanching of the tissue and burning sensation on impingement of the nerve. Because studies about the immediate complications of LA administration were conducted before 1980, more recent data regarding this procedure are needed. ⋯ LA is a safe procedure when the appropriate technique is used. It is even safer when an inferior alveolar nerve block is administered.

Randomized Controlled Trial Clinical TrialContinuous interscalene brachial plexus block for postoperative analgesia following shoulder surgery.
Severe postoperative pain is a well-known problem following shoulder surgery. This study evaluates the clinical efficacy of continuous interscalene brachial plexus block, patient-controlled analgesia, and morphine (i.v. and i.m.) for postoperative analgesia in this setting. ⋯ Successful continuous interscalene brachial plexus block provides very good pain relief following shoulder surgery and is superior to the other methods studied. However, we were unable to demonstrate a correlation between VAS pain scores and stress indicators in metabolic, circulatory and respiratory parameters.

To describes a technique of indwelling interscalene catheter placement and to evaluate its complications. ⋯ Indwelling catheter placement into the brachial plexus sheath as described in this communication was effective and associated with few complications.

Randomized Controlled Trial Clinical TrialBilateral infraorbital nerve block is superior to peri-incisional infiltration for analgesia after repair of cleft lip.
Cleft lip repair is a common operation in infants and requires that the child is pain-free during the postoperative period so that handling does not affect the integrity of the delicate surgical site. This study was designed to compare the efficacy and duration of effect of 0.125% bupivacaine given preoperatively as a bilateral infraorbital nerve block with peri-incisional infiltration of the same local anaesthetic for postoperative analgesia in cleft lip repair. It was a randomised, double blind, prospective study in 30 children aged 4-20 months (ASA grade 1). ⋯ The analgesic requirement in group B became significant at two hours postoperatively, while group A had significant analgesic requirements only after eight hours. The significant rise in heart rate and blood pressure that accompanied tracheal intubation in both groups suggested that while both methods of analgesia may be adequate to prevent responses to skin incision, they do not substitute for adequate systemic analgesia during the operation. We conclude that infraorbital nerve block with 0.125% bupivacaine provides better and more prolonged analgesia than peri-incisional infiltration in cleft lip repair.

Selective spinal nerve block is a useful tool in today's multidisciplinary approach to the diagnosis and treatment of low back pain. The indications, sources of spinal pain, block technique, result interpretation, complications and clinical applications relevant to the subject are discussed. ⋯ In some cases, therapeutic effect including that from surgical intervention can be achieved selectively at the symptomatic root. However, controversy remains and therefore well designed clinical studies are needed to provide more information about the validity of this diagnostic and therapeutic modality.
