Randomized Controlled Trial Clinical TrialSphenopalatine ganglion block for the treatment of myofascial pain of the head, neck, and shoulders.
This study examined the effectiveness of sphenopalatine ganglion block (SPGB) for myofascial pain syndrome of the head, neck, and shoulders using a double-blind, placebo-controlled, crossover study design with comparison to an internal standard consisting of trigger point injections (TPI). ⋯ This study suggests that SPGB with 4% lidocaine is no more efficacious than placebo and less efficacious than administration of standard trigger point injections in the treatment of myofascial pain of the head, neck, and shoulders.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of remifentanil and propofol infusions for sedation during regional anesthesia.
Patients treated with regional anesthesia often require concomitant medication for comfort and sedation. Propofol is widely used for this purpose. Remifentanil, a new ultra-short-acting opioid, exhibits at low doses distinct sedative properties that may be useful for supplementation of regional anesthesia. This study compared the effectiveness of remifentanil and propofol infusions for providing sedation during regional block placement and surgery. ⋯ When titrated to the same sedation level, remifentanil provided a smoother hemodynamic profile than propofol during regional anesthesia. The frequent occurrence of remifentanil-induced respiratory depression requires cautious administration of this agent. The incidence of adverse reactions seen with both agents during and after their administration makes the management of such sedative infusion techniques difficult.
