title: [Thoracic paravertebral block in the PACU for immediate postoperative pain relief after video-assisted thoracoscopic surgery].
abstract: Objective:To investigate the effectiveness and safety of the thoracic paravertebral block(TPVB) in the post postanesthesia care unit(PACU) for patients suffered moderate to severe pain after Video-Assisted Thoracoscopic Surgery(VATS).Methods:78 atients who complained moderate to severe pain on arrival to PACU after VATS were randomly assigned into two groups: thoracic paravertebral block treatment group(P group) and sufentanil treatment group(S group). The VAS Pain score at rest and movement, heart rate, blood pressure, and pulse oximetry 1 hour after treatment and duration of patients staying in the PACU after treatment were recorded. VAS Pain score at rest and on coughing at 8, 24 and 48 hours after treatment were closely monitored. Sufentanil comsumption, patient satisfaction and related complications were also recorded.Results:A successful TPVB was achieved in all patients in P group without puncture related complications. The VAS pain scores at rest and on coughing 1 hour, 8 hours, 24 hours and 48 hours after treatment in P group were significantly lower than the patients in S group. Systolic blood pressure 1 hour after treatment in P group was also lower than the patients in S group(118mmHg±14mmHg vs 128 mmHg±14 mmHg,P=0.021). SPO2 1 hour after treatment in P group was much higher than the patients in S group(95%±3% vs 92%±4%,P=0.015). The duration of patients staying in the PACU after treatment in both groups were similar. Sufentanil comsumption, rate of vomiting and nausea was significantly less and satisfaction was better in P group than thoses in S group.Conclusion:In the postanesthesia care unit, TPVB could provide effective and safe analgesia therapy for patients suffered from moderate to severe pain after VATS.
