Prevention of surgical site infection and appropriateness of antibiotic prescribing habits in plastic surgery

OBJECTIVES The use of antimicrobial prophylaxis against surgical site infection (SSI) is widespread in plastic surgery, while results from prospective randomised controlled trials in guiding antibiotic use are lacking. The purpose of this study was to identify the incidence and risk factors for SSI in plastic surgery, and to evaluate the appropriateness of prophylactic antibiotic prescribing habits in a tertiary university centre. METHODS A retrospective chart review was conducted over a 6-month period. Co-morbidities, types of procedure, prophylactic antimicrobial administration, SSI rates, and clinical outcomes were evaluated. RESULTS The incidence of SSI was 9.3% for 335 procedures. The cumulative incidence of SSI for breast surgery (n=80) was 16.3%, with a 78.8% prescription rate. For head and neck procedures (n=68), the incidence of SSI was 10.3%, with 80.9% of patients receiving antibiotic prophylaxis. For hand and upper limb procedures (n=170), 70.6% of patients received antimicrobial prophylaxis, with a 4.7% SSI incidence. According to category A prophylaxis guidelines published in the plastic surgery literature, over prescribing was identified in 27.5% of breast, 61.8% of head and neck, and 19.4% of hand and upper limb procedures. CONCLUSIONS This is the first study evaluating appropriateness of antimicrobial prophylaxis use by plastic surgeons. Despite widespread use of prophylactic antibiotics, significant SSI rates were still present and frequently responsible for re-hospitalisations and re-interventions. The appropriateness of administration and indications for perioperative prophylactic antibiotic use must be evaluated.

Preliminary evaluation of infraclavicular catheters inserted using ultrasound guidance: through-the-catheter anesthesia is not inferior to through-the-needle blocks.

Background and Objectives: This prospective study compared the initial block quality and surgical anesthesia rates of ultrasound-guided infraclavicular blocks with local-anesthetic injected through a catheter versus through a needle. We hypothesized that positioning of the catheter immediately posterior to the axillary artery would produce through-the-catheter (TTC) anesthesia with rates of complete block not inferior to through-the-needle (TTN) injection. Methods: Eighty patients undergoing hand or forearm surgery extensive enough to require regional anesthesia were randomized into 2 groups of 40. In group TTN, local anesthetic was deposited posterior, lateral, and medial to the axillary artery using as few injections as necessary. In group TTC, a 20-gauge, multiorifice catheter was positioned between the posterior wall of the axillary artery and the posterior cord of the brachial plexus. All blocks were performed by use of ultrasound visualization with a 6-MHz to 10-MHz 38-mm linear probe. Local-anesthetic solution consisted of 0.5 mL/kg lidocaine 2% with epinephrine. Sensory and motor blocks, as well as supplementation rates, were evaluated for the musculocutaneous, median, radial, and ulnar nerves. Results: Complete sensory block of all nerve territories was achieved in 92% of patients in group TTN and 90% in group TTC (P = .51). In group TTN, 90% of patients had satisfactory anesthesia for surgery (no discomfort and no need for anesthetic supplementation of any type) compared with 92% in group TTC (P = .51). Conclusion: Ultrasound-guided TTC infraclavicular block produced perioperative anesthesia that was not inferior to a TTN technique.

Outcomes in the Management of Sternal Dehiscence by Plastic Surgery : A Ten-Year Review in One University Center

Purpose:Infection rates following median sternotomy vary between 0.2% and 10%. These cases are associated with morbidity and mortality rates between 10% and 25% and 5% and 20%, respectively. The purpose of this study was to evaluate patient outcomes following plastic surgery correction of sternotomy dehiscence (SD). Methods:All patients operated on for an SD following coronary artery bypass graft surgery (CABG), between 1995 and 2005, with 1 or more flaps, were included. Results:Eighty cases were identified over a 10-year period. The mean age was 64 (±9.1) years. Two or more procedures were required in 17.5% of patients, and the mortality rate within 30 days was 12.5%. Significant variability was revealed between the cumulative mortality rates of plastic surgeons, from 0.0% to 50.0%. Multiple associations were identified for poor outcome, including chronic renal insufficiency and early mortality, and obesity with risk of reintervention. Conclusion:Although patients who undergo surgical correction of a deep sternal infection usually tolerate their intervention well, the mortality within 30 days remains high. This study has identified several factors explaining morbidity and mortality in this patient population.

Evaluation of factors influencing confidence and trust in the patient-physician relationship: A survey of patient in a hand clinic

OBJECTIVES The purpose of this study was to identify the skills found most important to gain patients trust from a patients perspective. METHODS One hundred and twenty-two patients were surveyed prospectively using a questionnaire assessing professionalism, physical environment, verbal and non-verbal communication skills. Factors required to establish a trusting patient-surgeon relationship were ranked in order of importance before and after initial consultation with a surgeon in a hand surgery clinic model. RESULTS No significant relationship was identified between gender, age, education or income, and answers provided by respondents. Technical ability, verbal communication skills and respect of patients autonomy by the physician were found most important. CONCLUSION The visit with the surgeon significantly affected the ranking of some of the skills deemed important. Patients view respect of autonomy and verbal communication skills as the most important attributes when developing trust and confidence in a surgeon, followed by technical proficiency.

Wound healing assessment: does the ideal methodology for a research setting exist?

Introduction:Studies on dressings frequently measure wound healing to demonstrate performance. Knowledge of existing methodologies available for wound healing assessment, including their advantages and limitations, is paramount when evaluating the literature on dressings. Methodology:Medline and Cochrane databases were searched for wound healing assessment methodologies used in research or in clinical practice. Results:Twenty-nine methodologies were identified and classified into 8 categories: scales (n = 4), one-dimensional measurements (n = 2), area measurements (n = 4), volume measurements (n = 6), 3-dimensional wound reproduction systems (n = 5), methodologies based on wound physical characteristics (n = 3), rates and surrogates end point calculated from variation in wound dimensions (n = 4), and time to wound healing (n = 1). The main problems encountered during wound healing assessment include the following: boundary definition, assessors contact with the wound, irregular wound shape, and difficulty in evaluating early healing. Conclusion:At this time, an ideal methodology does not exist. Research in this area is lacking and should be the focus in wound healing evaluation.

Modified flexor digitorum superficialis slip technique for A4 pulley reconstruction

We describe a variation in the A4 pulley reconstruction technique using one slip of the flexor digitorum superficialis insertion and report the results of a biomechanical analysis of this reconstruction in cadavers. While conserving the distal bony insertion, one slip of flexor digitorum superficialis is transferred over the flexor digitorum profundus tendon and sutured to the contralateral superficialis slip insertion. This creates a new pulley at the base of the original A4 pulley that can be adjusted to accommodate an FDP repair of increased bulk. We found a 57% reduction in excess excursion due to bowstringing when compared with no repair. Furthermore the repairs were sturdy, 94% of specimens maintaining their integrity when a proximally directed force of 50 N was applied.

Mechanical failure of a Fogarty catheter in a microsurgical procedure: A case report

Although microvascular free-tissue transfer has become a reliable reconstructive method, vascular compromise of the flap necessitating surgical exploration and attempts at flap salvage commonly occurs. Thrombectomy using Fogarty vascular catheters can be used in the setting of vascular pedicle thrombosis. However, this is not without potential complications. The following report describes a case in which the use of a Fogarty vascular catheter during a thrombectomy for microsurgical flap salvage resulted in complete separation of the balloon from the catheter.
