Abstract

Despite its effectiveness in other surgeries studies on continuous epidural block in upperextremity surgery are rare because of technical difficulties and potential complications This study compared postoperative analgesic efficacy and safety of ultrasoundguided continuous interscalene brachial plexus block UCISB and fluoroscopyguided targeted continuous cervical epidural block FCCEB in arthroscopic rotator cuff repair ARCRSeventyfive patients were randomly and equally assigned to groups FCCEB 02  UCISB75 075  and UCISB20 02  according to the initial ropivacaine dose 8 ml The background infusion 02  ropivacaine at 5 ml/h bolus 3 ml of 02  ropivacaine and lockout time 20 min were consistent Respiratory effects respiratory discomfort modified Borg scale ventilatory function and hemidiaphragmatic excursion ultrasound analgesic quality pain severity at rest and motion attempt VASR and M number of boluses analgesic supplements and sleep disturbance neurologic effects procedural discomfort satisfaction and adverse effects were evaluated preprocedurally and up to 72 h postoperativelyFCCEB caused less respiratory depression and sensorimotor block but had less analgesic efficacy than UCISBs P  005 FCCEB caused nausea vomiting and dizziness more frequently P  005 and had lower patient satisfaction than UCISBs P  005 UCISB75 can cause severe respiratory distress in patients with lung disorders Other variables were not significantly different between the groups
