Clinical Results
After continuous SAPB for 2, 6, 12, 24, and 48 hours, VAS scores were
obtained and recorded during ward follow-up. From the comparison of VAS
scores, the VAS scores at rest and on coughing were lower in Group H at
12, 24, and 48 hours than in Group L (Table 2). The number of rescue
analgesia procedures was comparable between the two groups (10 patients
in Group L and 8 patients in Group H, P =0.597). There were no
significant differences in the incidence of postoperative
nausea/vomiting, hypoxemia, or postoperative hospital stay between the
two groups. No postoperative wound infections occurred in either group
(Table 3).
