Background and Aims: Pectoral nerve blocks gained increasing recognition for adequate postoperative pain relief following breast surgery. Traditionally, anaesthetist administered preoperatively under ultrasound guidance, which added significantly to the total procedure time. We studied the effectiveness of intraoperative direct vision pectoral nerve block and reduction of total theatre time. Methods: We provided questionnaires to the eligible patients who underwent a mastectomy and or axillary node clearance from August 2018 to May 2019. All the patients had an intra-operative pectoral 1 and serratus plane (Pecs) block. Participants documented pain score twice daily, episodes of nausea or vomiting and type and dose of analgesia for the first seven postoperative days. We compiled and grouped the results into postoperative days 1 -2 and 3 -7 for data analysis. Results: Patients reported generally low levels of pain, with a median pain score of 1.75 out of 10 for postoperative days 1 -2 (IQR 4). The score decreased to 0.7 for days 3 -7 postoperatively (IQR 3) suggesting that most patients had generally minimal levels of pain apart from a few outliers. The average injection time for PECs blocks was 5 minutes, significantly less than USS guided techniques of 20 -30 minutes. Conclusions: Our data suggest that nerve blocks under direct vision offer satisfactory efficacy in postoperative analgesia with minimal nausea and vomiting. This is in addition to substantial benefits in operative efficiency and reduction of total procedure time.
Summary:
Wound coverage of exposed vascular bypasses after acute limb revascularization may not be immediately possible, while delay may create a hostile environment for the bypass graft. The use of negative-pressure wound therapy may not be possible because of extrinsic compression. Temporary use of acellular dermal matrix can help salvage upper extremity. We present 2 patients with brachial artery transection secondary to blunt trauma, who had revascularization with interposition saphenous vein grafts. We used acellular dermal matrix as temporary coverage for the exposed arterial bypass grafts to allow for patient stabilization, serial debridement, and demarcation of the surrounding tissues before definitive coverage. Additionally, the use of negative-pressure wound therapy caused diminished pulses in the bypass graft, creating the need for reliable temporary coverage. The acellular dermal matrix dressing was left in place until definitive closure was possible. Both patients underwent successful wound coverage with fasciocutaneous flaps without disruption, thrombosis, or infection of the bypass grafts. Follow-up at 6 months demonstrated good healing and excellent function. The use of the acellular dermal matrix provides temporary coverage of vital structures until definitive reconstruction can be performed.
Patients with connective tissue diseases have been shown to be at higher risk for complications after surgery. In this report, we describe a case of a patient with long-standing, stable systemic sclerosis (SS), diagnosed approximately 28 years ago, who underwent nipple-sparing mastectomy and immediate reconstruction with prepectoral tissue-expander placement. She subsequently had uneventful implant-based reconstruction with adjunctive fat grafting. To our knowledge, this is the first reported case of implantbased prepectoral reconstruction after mastectomy in a patient with SS.
Background:
There is increasing evidence that lidocaine is toxic to adipocytes and their precursors, which can contribute to the variability in fat graft resorption. Erector spinae plane (ESP) block is a new technique to provide analgesia of the trunk and would avoid lidocaine at the fat graft donor site. The aim of this study was to compare the efficacy of ESP block versus tumescent local anesthesia (TLA).
Methods:
A retrospective review was performed for all patients who underwent autologous fat grafting from the abdomen at the University of New Mexico Hospital between February 2016 and March 2019. These patients received either ESP block or TLA during abdominal fat harvest. The primary endpoints were intraoperative, postoperative, and total morphine equivalents.
Results:
There was no difference in the mean intraoperative, postoperative, and total morphine equivalents administered between the ESP and TLA groups.
Conclusions:
ESP block is equivalent to TLA for analgesia when using an abdominal donor site for fat harvest. ESP block should be considered in fat-grafting cases to avoid the potential toxicity of lidocaine to the viability of adipocytes and preadipocytes.
