Impact of liposome bupivacaine on the adequacy of pain management and patient experiences following aesthetic surgery: Results from an observational study.

BACKGROUND: Despite the efficacy of opioid analgesics for postsurgical pain, they are associated with side effects that may complicate recovery. Liposome bupivacaine is a prolonged-release formulation of bupivacaine approved for intraoperative administration at the surgical site for postsurgical analgesia. OBJECTIVES: To evaluate the effect of a single intraoperative administration of liposome bupivacaine on postsurgical pain, opioid use and opioid-related side effects in subjects undergoing breast surgery and/or abdominoplasty. METHODS: In the present phase IV, multicentre, prospective observational study, subjects received a single intraoperative administration (266 mg) of liposome bupivacaine. Rescue analgesia was available to all subjects as needed. Outcome measures, assessed through postoperative day 3, included postsurgical pain intensity (11-point numerical rating scale), opioid consumption and overall benefit of analgesic score. Results were evaluated comparing investigators' previous experience with similar surgeries. RESULTS: Forty-nine subjects entered the study: 34 underwent breast surgery only and 15 underwent abdominoplasty with or without breast surgery (six underwent breast surgery in addition to abdominoplasty). Mean numerical rating scale pain scores remained ≤4.3 from discharge through postoperative day 3. Median daily oral opioid consumption was approximately 1.0 tablet postoperatively on the day of surgery and was approximately 2.0 tablets by postoperative day 3. Mean overall benefit of analgesic score ranged between 2.8 and 4.9 throughout the study. CONCLUSION: In this particular subject population, liposome bupivacaine was associated with low pain intensity scores and reduced opioid consumption compared with the investigators' previous experiences. Subjects' satisfaction with postsurgical analgesia was high, with a low burden of opioid-related side effects.

HISTORIQUE: Malgré l'efficacité des opioïdes pour soulager la douleur postchirurgicale, des effets secondaires peuvent compliquer le rétablissement. La bupivacaïne liposomique est une formulation à libération prolongée approuvée pour l'administration peropératoire d'une analgésie postchirurgicale au site opératoire. OBJECTIFS: Évaluer l'effet de l'administration peropératoire d'une seule dose de bupivacaïne liposomique sur la douleur postchirurgicale, ainsi que sur l'utilisation d'opioïdes et leurs effets secondaires chez des sujets subissant une chirurgie mammaire, une abdominoplastie ou les deux interventions. MÉTHODOLOGIE: Dans le cadre de la présente étude d'observation prospective et multicentrique de phase IV, les sujets se sont fait administrer une seule dose peropératoire de bupivacaïne liposomique (266 mg). Tous les sujets pouvaient recevoir une analgésie de secours, au besoin. Les mesures des résultats, évaluées jusqu'au troisième jour postopératoire, incluaient l'intensité de la douleur postchirurgicale (sur une échelle numérique de onze points), la consommation d'opioïdes et les bienfaits globaux du score analgésique. Les chercheurs ont évalué les résultats en les comparant à leur expérience de chirurgies similaires. RÉSULTATS: Quarante-neuf sujets ont participé à l'étude : 34 ont subi seulement une chirurgie mammaire et 15, une abdominoplastie accompagnée ou non d'une chirurgie mammaire (six ont subi une chirurgie mammaire en plus de l'abdominoplastie). Les scores de douleur moyens sur l'échelle numérique ne dépassaient pas 4,3 entre le congé et le troisième jour postopératoire. La consommation quotidienne médiane d'opioïdes par voie orale après l'opération était d'environ 1,0 comprimé le jour de la chirurgie et d'environ 2,0 comprimés le troisième jour postopératoire. Les avantages globaux moyens du score analgésique se situaient entre 2,8 et 4,9 tout au long de l'étude. CONCLUSION: Au sein de cette population de sujets, la bupivacaïne liposomique s'associait à de faibles scores d'intensité de la douleur et à une consommation réduite d'opioïdes par rapport aux expériences passées des chercheurs. Les sujets étaient très satisfaits de l'analgésie postchirurgicale et présentaient un faible fardeau d'effets secondaires liés aux opioïdes.

Anesthesia duration as a marker for surgical complications in office-based plastic surgery.

BACKGROUND: Office-based plastic surgery has continued to rise in the past 2 decades with the increased demand for cosmetic surgery. Although several large studies have shown the safety of office-based surgery, current regulations place some restrictions on ambulatory office-based surgical facilities. To provide further evidence-based literature on the safety of office-based plastic surgery, we examine surgical complication rates as a function of anesthesia duration. METHODS: This is a retrospective review of 2595 patients who underwent office-based plastic surgery procedures between October 2000 and January 2005. All patients received general anesthesia for a broad range of cosmetic surgeries. The primary measured outcome was minor and major surgical complications. Complication rates were examined as a function of anesthesia duration of less than or greater than 4 hours. The follow-up period was 30 days. Statistical analysis was completed using SPSS v.19. RESULTS: Most of the patients were female with an average age of 41 years. An increase in the occurrence of minor surgical complications such as postoperative nausea and vomiting (2.8% vs 5.7%, P=0.0175) and urinary retention (0.7% vs 7.6%, P<0.0001) was noted in the greater than 4-hour anesthesia duration group. Overall, there were 66 (2.5%) patients that required reoperation because of surgical complications with no statistical difference between the 2 groups (P=0.098). The only major morbidities were 1 pulmonary embolism (<4 hours) and 1 deep vein thrombosis (>4 hours). Five (0.19%) patients were admitted to the hospital during the follow-up period for surgical and/or medical management (3 hematomas, 1 deep vein thrombosis, and 1 pulmonary embolism). There were no cases of reintubation, major cardiac complications, or death in this series. CONCLUSIONS: Duration of general anesthesia in office-based plastic surgery does not seem to be an indicator of major morbidity and mortality. Although minor complications such as postoperative nausea and vomiting and urinary retention were higher in patients with anesthesia greater than 4 hours, there was no significant increase in major complications. Change in surgical venue would not likely alter the outcome of the increase in minor complications. Therefore, anesthesia duration should not be used as a guideline for safety of office-based plastic surgery.

Do progressive tension sutures really decrease complications in abdominoplasty?

The purpose of this study is to evaluate the efficacy of progressive tension sutures (PTS) in preventing or reducing seroma formation and local wound complications in patients undergoing abdominoplasty. Forty-nine patients who underwent abdominoplasty procedures with the use of PTS were retrospectively compared with a historical control group of 54 patients who underwent standard abdominoplasty. Primary outcomes measured were seroma formation and local wound complications, including hypertrophic scar formation, umbilical distortion, and wound necrosis. Secondary outcomes were all other complications and time to drain removal. Overall complication rates and local wound complication rates were significantly reduced with the addition of PTS to abdominoplasty. Seroma formation and the time to drain removal were reduced in the PTS group, but the findings were not statistically significant.

Head and neck reconstruction with a second free flap following resection of a recurrent malignancy.

A retrospective analysis of 12 patients with a head and neck tumor recurrence within a previous free flap treated with extirpation and a second free flap is reported. A 15-year experience at Mayo Clinic, Rochester, from 1988 to 2003 of 12 patients (5 men, 7 women) who underwent 25 free flaps is reviewed. The overall flap survival rate was 92%, with a 100% survival rate in the first free-tissue transfer and 85% survival rate in the second free-tissue transfer. There was 1 minor complication (8%) and there were 2 major complications (15%) among the second free flaps. Overall, 10 of 13 (77%) second free flaps were anastomosed to ipsilateral neck vessels. Moreover, in 5 of 13 cases (38%) the same artery and in 7 of 13 cases (54%) the same vein were used for both the first and second free flaps. Reconstruction of the head and neck with a second free flap in patients with a recurrent tumor is safe and effective. The original recipient vessels can often be used for the second reconstruction.

Vaginal reconstruction following resection of primary locally advanced and recurrent colorectal malignancies.

HYPOTHESES: Vertical rectus abdominus myocutaneous flap reconstruction facilitates healing within the radiated pelvis and preserves the possibility of subsequent sexual function in patients with colorectal cancer who require partial or complete resection of the vagina. DESIGN: A retrospective review of a consecutive series of patients. SETTING: A tertiary referral center. PATIENTS: All patients undergoing surgical treatment of locally advanced or recurrent colorectal cancer and vertical rectus abdominus myocutaneous flap reconstruction of the vagina. INTERVENTION: Vertical rectus abdominus myocutaneous flap reconstruction. MAIN OUTCOME MEASURES: Operative feasibility, complications, and sexual function. RESULTS: Twelve patients underwent extended resection for primary locally advanced or recurrent colorectal cancer including total or near total vaginectomy. Median age was 47 years. Tumors included 9 rectal adenocarcinomas, 2 anal squamous cell carcinomas, and 1 recurrent cecal adenocarcinoma. Surgical procedures included 8 abdominoperineal resections with posterior exenteration; resection of pelvic tumor and partial vaginectomy in 2 patients with previous abdominoperineal resection; 1 total exenteration; and 1 total proctocolectomy with posterior exenteration. The average operative time for tumor extirpation, irradiation, and reconstruction was more than 9 hours and all patients required blood transfusions. Despite 2 patients having superficial necrosis and 4 having mild wound infections, no patient required reoperation and all achieved complete healing. Five patients reported resuming sexual intercourse. CONCLUSIONS: The vertical rectus abdominus myocutaneous flap can be successfully used for vaginal reconstruction following resection of locally advanced colorectal cancer. It provides nonirradiated, vascularized tissue that fills the pelvic dead space, allows for stomal placement, and provides a chance for sexual function.
