R. Aantaa et al., TRANSARTERIAL BRACHIAL-PLEXUS ANESTHESIA FOR HAND SURGERY - A RETROSPECTIVE ANALYSIS OF 346 CASES, Journal of clinical anesthesia, 6(3), 1994, pp. 189-192
Study Objectives: To study the safety and efficacy of the transarteria
l approach to brachial plexus block with 60 to 70 ml of local anesthet
ic solution, and to compare the success and complication rates of this
block performed by experienced or inexperienced anesthesiologists. De
sign: Retrospective analysis of 346 records of ASA physical status I-I
V patients who underwent elective unilateral orthopedic upper limb sur
gery with transarterial plexus anesthesia. Setting: University teachin
g hospital. Measurements and Main Results: Blood pressure (BP) and hea
rt rate were measured at 5-minute intervals. Analgesia was registered
as successful, incomplete, orfailed. Any patient complaints or adverse
reactions were recorded. The first 60 ml of local anesthetic provided
surgical analgesia to 64% of patients. With a supplemental 10 ml of a
nesthetic, the overall success rate was 94%, with only 19 of 346 patie
nts requiring general anesthesia. Experience in performing the block i
ncreased the success rate from 90% to 98% (P < 0.001). Six patients ex
perienced either nausea or a transient BP decrease that did not requir
e medication. There was no record of toxic or other serious adverse re
action. Conclusions: Transarterial brachial plexus block administered
with a 60 to 70 ml dose of local anesthetic provides surgical analgesi
a for hand surgery with an excellent success rate and without serious
adverse effects.
