GARCIA CEBALLOS, Erlinda; GARCIA GARCIA, Gerardo Luis; MELIS SUAREZ, Aneite  e  CABANA SALAZAR, José Antonio. Metabolic and clinical correlation in traumatic upper limb surgery and continuous brachial plexus block. Rev Cub Med Mil [online]. 2013, vol.42, n.1, pp. 72-79. ISSN 0138-6557.

Objective: to assess changes in metabolic clinical correlation with traumatic upper limb surgery in patients receiving regional-analgesia anesthesia by continuous brachial plexus block (DNB). Methods: 60 patients were studied. All of them were ASA-I, and they were placed into two equal groups: G (control), general anesthesia and systemic analgesia with dipyrone 1.2 g IM every 6 hours, and B (study), DNB regional anesthesia (axillary or supraclavicular) with 100 mg of bupivacaine and analgesia with the same local anesthetic every 6 hours. Clinical and metabolic alterations were correlated 24 hours postoperatively by clinical examination and capillary blood gasometry in both upper limbs. Results: most of the subjects studied were male and most of them aged 30-44 and 45-59 years in both groups (p = 0.05). Simple and multiple fractures accounted for 60% of the total sample in groups G and B respectively (p = 0.05) and emergency treatment was required in both groups (p = 0.05). 70 % of patients in group G felt the injured limb cold, and 13.3 % in group B (p = 0.01). A slow capillary refill was found in 53.3 % of patients in group G and 10 % in B (p = 0.01) and 56.7 and 10% patients in groups G and B (p = 0.01) showed pale hand respectively. HbO2 £ 89 % was found in the injured limb in 60 and 6.7 % patients in groups G and B respectively (p = 0.01), and a difference HbO2 > 5 % was corroborated among the upper limbs: 76.7 % patients in group G and 16.7 % in B (p = 0.01). Conclusions: the method of regional anesthesia-analgesia by continuous brachial plexus block is superior in terms of advantages, as there is a reduction in terms of changes in the metabolic clinical correlation in injured upper limbs.
