RESUMO

Facial lacerations are commonly encountered in emergency departments and require effective management to optimise aesthetic outcomes. Non-resorbable sutures are traditionally favoured for their tensile strength and minimal inflammatory response, despite the inconvenience of the required follow up for removal. This single-centre, single-blinded randomised controlled trial aimed to compare the clinical efficacy and cost-effectiveness of resorbable (Vicryl Rapide) versus non-resorbable (Ethilon) sutures for the closure of facial lacerations in adults. Between November 2021 and February 2023, 200 adult patients presenting with facial lacerations were randomly allocated to either resorbable or non-resorbable sutures. Outcomes assessed included aesthetic results via the Visual Analogue Scale (VAS) and Hamilton Scar Scale, patient-reported satisfaction using the Patient Scar Assessment Questionnaire (PSAQ), complication rates, and cost analysis. No significant differences were found in mean VAS scores between the two groups in both modified intention-to-treat and per-protocol analyses. The majority of patients reported high satisfaction levels. Early complication rates were significantly higher in the non-resorbable group at the one-week follow up, with no long-term differences noted. Preliminary cost analysis indicated a more than five-fold cost saving with resorbable sutures. Resorbable sutures provide a viable and cost-effective alternative to non-resorbable sutures for adult facial lacerations, with comparable aesthetic outcomes and patient satisfaction. Their use could reduce healthcare burdens by eliminating the need for follow-up suture removal, supporting broader adoption in clinical practice.

RESUMO

A low approach to the interscalene block (LISB) deposits local anesthetic farther caudad on the brachial plexus compared with the conventional interscalene block (ISB). We compared the efficacy of LISB and ISB in achieving anesthesia of the distal extremity in 254 patients having upper extremity surgery. The most frequent elicited motor response was the deltoid for ISB and wrist for LISB. There was significantly greater sensory-motor block of regions below the elbow with the LISB compared with ISB (P < 0.001 for both sensory and motor coverage). Our data indicate that LISB results in a higher incidence of distal elicited motor response and greater sensory-motor blockage of the wrist and hand.

RESUMO

BACKGROUND: : In a pilot study of awake volunteers, intraocular pressure (IOP), choroid layer thickness, and optic nerve diameter were shown to increase in the prone position over 5 h with a nonsignificant trend of attenuation using a 4-degree increase of table inclination. These effects have previously not been isolated from anesthetic and fluid administration over a prolonged period, using an adequate sample size. METHODS: : After institutional review board approval, 10 healthy volunteers underwent IOP measurement (Tono-Pen XL, Medtronic Solan, Jacksonville, FL) as well as choroidal thickness and optic nerve diameter assessment (Sonomed B-1000, Sonomed, Inc., Lake Success, NY, or the I System-ABD, Innovative Imaging, Inc., Sacramento, CA) on a Jackson table (Orthopedic Systems, Inc., Union City, CA), during 5 h horizontal prone and 5 h 4-degree reverse Trendelenburg positioning. Measurements were assessed as initial supine, initial prone, and hourly thereafter. Vital signs were recorded at each position and time point. RESULTS: : IOP, choroidal thickness, and optic nerve diameter were observed to increase with time in the prone position. A small degree of reverse Trendelenburg attenuated the increase in choroidal thickness but not IOP or optic nerve diameter. CONCLUSIONS: : Prolonged prone positioning increases IOP, choroid layer thickness, and optic nerve diameter independent of anesthetics and intravenous fluid infusion and 4 degrees of table inclination (15 cm of head to foot vertical disparity) may not attenuate these effects.

RESUMO

OBJECTIVE: Pulmonary artery (PA) flow reversal has been associated with poor outcome in patients with atriopulmonary (APC) and total cavopulmonary connection (TCPC) lateral tunnel (LT) Fontan modification. The authors studied PA flow after TCPC in relation to the incidence of early Fontan outcome and complications. DESIGN: A prospective observational study. SETTING: A university hospital. PARTICIPANTS: Pediatric patients undergoing a Fontan procedure. INTERVENTION: Nineteen patients were studied. PA flow was measured by pulse-wave Doppler during the surgery after chest closure. Patients were divided into 2 groups according to patterns of PA flow: group 1, positive (biphasic or continuous flow), and group 2, negative (with flow reversal component). The postoperative complications were recorded. MEASUREMENTS AND MAIN RESULTS: There were no deaths or reoperations for Fontan takedown. Ten patients had positive and 9 had negative flow. There were no differences between groups regarding age, weight, length of procedure, and cardiopulmonary bypass. The chest tube drainage in patients with negative flow was significantly longer than those in the positive-flow group (8.3 +/- 7.0 days in the negative-flow group v 2.8 +/- 1.7 days in the positive-flow group, p = 0.03). The total number of complications was higher in the negative-flow group compared with the positive-flow group (3.0 +/- 1.3 v 1.2 +/- 0.6, p = 0.003). The differences between groups in terms of pediatric intensive care unit and/or hospital length of stay did not reach statistical significance, possibly because of the low number of patients. CONCLUSION: PA flow pattern appears to be predictive of the length of postoperative chest tube drainage and the number of postoperative complications.

RESUMO

BACKGROUND: Video games have received widespread application in health care for distraction and behavior modification therapy. Studies on the effect of cognitive distraction during the preoperative period are lacking. We evaluated the efficacy of an interactive distraction, a hand-held video game (VG) in reducing preoperative anxiety in children. METHODS: In a randomized, prospective study of 112 children aged 4-12 years undergoing outpatient surgery, anxiety was assessed after admission and again at mask induction of anesthesia, using the modified Yale Preoperative Anxiety Scale (mYPAS). Postoperative behavior changes were assessed with the Posthospital Behavior Questionnaire (PHBQ). Patients were randomly assigned to three groups: parent presence (PP), PP+a hand-held VG, and PP+0.5 mg.kg-1 oral midazolam (M) given>20 min prior to entering the operating room. RESULTS: There was a statistically significant increase in anxiety (P<0.01) in groups M and PP at induction of anesthesia compared with baseline, but not in VG group. VG patients demonstrated a decrease in anxiety from baseline (median change in mYPAS -3), the difference compared with PP (+11.8) was significant (P=0.04). The change in anxiety in the M group (+7.3) was not statistically different from other groups. Sixty-three percent of patients in VG group had no change or decrease in anxiety after treatment, compared with 26% in M group and 28% in PP group (P=0.01). There was no difference in anxiety changes between female and male patients. CONCLUSIONS: A hand-held VG can be offered to most children as a low cost, easy to implement, portable, and effective method to reduce anxiety in the preoperative area and during induction of anesthesia. Distraction in a pleasurable and familiar activity provides anxiety relief, probably through cognitive and motor absorption.

RESUMO

BACKGROUND: Geographic location is not acknowledged as a stratifying factor that can directly affect drug potency, because drugs are still licensed with the same recommended dose for different geographic regions. The aim of the current study was to compare the potency and duration of action of rocuronium bromide in 54 patients in three countries with different life habits, diet, and ambient conditions, namely white Austrians, white North Americans, and Han Chinese in China. METHODS: Neuromuscular block of six consecutive 50-microg/kg rocuronium incremental doses followed by 300 microg/kg was evaluated using the Relaxometer mechanomyograph (Groningen University, Groningen, Holland). Dose-response curves were created using log-dose-probit transformation. The authors compared rocuronium bromide ED50, ED90, and ED95 (effective doses required for 50%, 90%, and 95% first twitch depression, respectively) as well as Dur25 and Dur0.8 (times from last incremental dose administration until 25% first twitch and 0.8 train-of-four ratio recovery, respectively) in patients of the three countries. RESULTS: Rocuronium ED50, ED90, and ED95 were significantly higher in Austrian patients (258 +/- 68, 530 +/- 159, and 598 +/- 189 microg/kg) and Chinese patients (201 +/- 59, 413 +/- 107, and 475 +/- 155 microg/kg) compared with American patients (148 +/- 48, 316 +/- 116, and 362 +/- 149 microg/kg, respectively). Dur25 and Dur0.8 were significantly shorter in Austrian patients (22.3 +/- 5.5 and 36.9 +/- 12.8 min) and Chinese patients (30.4 +/- 7.5 and 45.7 +/- 15.9 min) compared with American patients (36.7 +/- 8.5 and 56.2 +/- 16.7 min, respectively). CONCLUSIONS: The authors demonstrated a significant difference in rocuronium potency and duration of action among patients in the three countries. Larger studies are required for determining dosage recommendations for different geographic regions.

RESUMO

During orthotopic liver transplantation a patient received epsilon-aminocaproic acid and clotting factors. Shortly after hepatic artery clamping the patient developed a massive intracardiac/intravascular thrombosis that resulted in cardiac arrest. After diagnosis by transesophageal echocardiography, the patient was treated with recombinant tissue plasminogen activator through a central venous catheter advanced into the right atrium. After treatment with recombinant tissue plasminogen activator, the patient's hemodynamic status improved, permitting the liver transplant to be completed. The patient was ultimately discharged to home. We report the successful intraoperative resuscitation of a patient with acute intracardiac/intravascular thrombosis during an orthotopic liver transplantation using thrombolytic therapy.

RESUMO

PURPOSE: The objective of this prospective descriptive study was to report our experience with an alternative general anesthetic technique, using sevoflurane for the pediatric patient, in an ambulatory setting. PATIENTS AND METHODS: Twenty consecutive pediatric patients participated over a 4-month period. A general anesthetic technique, using mask induction with sevoflurane and maintenance with a nasal trumpet as airway, was used throughout the surgical procedure. A standard anesthesia and recovery record was made for each patient; this included observations for untoward effects and complications. RESULTS: The average time for induction of anesthesia was 95 seconds, time from termination of sevoflurane to eye opening was 8 minutes, and duration of recovery was 30 minutes. Procedure time for each case did not exceed 10 minutes. Two patients had transient tachycardia. CONCLUSIONS: The results of this prospective descriptive study indicate that this technique is an effective and acceptable alternative to other modalities for the control of apprehension and fear in the pediatric patient in an ambulatory oral and maxillofacial facility.

RESUMO

PURPOSE: To highlight the management of a Jehovah's witness surgical patient presenting for cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest. CLINICAL FEATURES: A 47-yr-old male, Jehovah's Witness, with renal cell carcinoma was admitted for left radical nephrectomy and excision of tumour thrombus extending into the junction of the inferior vena cava (IVC) and right atrium (RA). The preoperative goals were to maximize red blood cell mass, delineate the extent of tumour extension and develop a surgical plan incorporating blood conservation strategies to minimize blood loss. A midline abdominal incision was made to optimize removal of the non-caval portion of the tumour from the intra-abdominal region. CPB and deep hypothermic circulatory arrest were instituted to aid in removing the tumour from the IVC and RA. Intraoperative blood conservation strategies included the use of acute normovolemic hemodilution, antifibrinolytics, cell salvage, point-of-care monitoring of heparin and protamine blood concentrations, leukocyte-depleting filter, and meticulous surgical techniques. The patient was successfully weaned from CPB and was transported to the cardiothoracic intensive care unit without complication. The patient was discharged home one week after the operation with a hemoglobin of 10.2 g x dL(-1) and a hematocrit of 31.2%. CONCLUSION: Multiple blood conservation techniques were employed to manage this Jehovah's Witness patient through complex cardiac surgery, which was previously denied to him at other institutions. The successful outcome of this patient, while respecting the right to refuse allogeneic blood products, is a result of a multidisciplinary collaboration as well as the application of established blood conservation techniques.
