Randomized Controlled Trial Comparative Study Clinical Trial
Transarterial brachial plexus anesthesia for hand surgery: a retrospective analysis of 346 cases.
To study the safety and efficacy of the transarterial approach to brachial plexus block with 60 to 70 ml of local anesthetic solution, and to compare the success and complication rates of this block performed by experienced or inexperienced anesthesiologists. ⋯ Transarterial brachial plexus block administered with a 60 to 70 ml dose of local anesthetic provides surgical analgesia for hand surgery with an excellent success rate and without serious adverse effects.
-
To determine the frequency of true and false alarms and to determine the frequency of alarm failures for various parameters when using a postanesthesia monitoring system. ⋯ The high frequency of apnea strongly motivates the use of continuous RR monitoring, preferably by flow-sensing techniques, since both central and obstructive apneas are then detected. Further study and development is necessary before pulse oximetry can be unconditionally recommended for postanesthesia monitoring.
-
To evaluate the relative contribution of general anesthesia alone and in combination with the surgical procedure to the pathogenesis of late postoperative hypoxemia. ⋯ General anesthesia in itself is not an important factor in the development of late postoperative constant and episodic hypoxemia, which instead may be related to the magnitude of trauma and/or opioid administration.
-
To assess the complications associated with the aspiration of sucralfate. ⋯ Acute complications associated with aspiration of sucralfate have been identified. In the laboratory setting, simulated aspiration of sucralfate led to acute lung injury.
-
To evaluate the independent effects of opioid induction and paralysis on changes in mixed venous oxygen saturation (SvO2). ⋯ Opioid anesthesia, not paralysis, increases SvO2. Most of the decrease in VO2 occurs from anesthesia, not paralysis. The direct relationship between CI and SvO2 no longer holds upon induction of anesthesia. Parallel changes in CI cannot be inferred based on SvO2 alone.
