Application of WALANT in Diaphyseal Plating of Forearm Fractures: An Observational Study.

Purpose: Wide-Awake Local Anesthesia No Tourniquet (WALANT) is a novel anesthesia technique in distal radius and ankle fracture fixation. However, to date, there are limited studies in diaphyseal plating of forearm fractures under WALANT. This research is to study the feasibility of the use of WALANT technique in plating of diaphyseal fractures of the forearm as well as peri-operative outcomes. Methods: Sixty-one adult patients who underwent diaphyseal plating of the forearm under WALANT between the period of January 2019 and January 2021. It consists of 31 radius fractures, 15 ulna fractures and 15 ipsilateral radius and ulna fractures. Outcomes evaluated were duration of stay, peri-operative numerical pain rating scale, peri-operative blood pressure and heart rate, visual analogue scale for anxiety, blood loss, surgery duration, adverse effect, patient's satisfaction and any complications at 6 months follow up. Results: Fifty-four patients (88.5%) were male and 7 patients (11.5%) were female with a mean age of 31.7 years (SD = 13.564). Thirty-eight out of 61 patients were totally pain free throughout the surgery. Ten (13%) patients reported pain during muscle dissection, 14 (18%) patients reported pain during bone manipulation and 12 (16%) patients reported pain during bone drilling. There was no significant difference in pain score between radius and ulna bones (P > .05). There was a significant change in blood pressure after LA infiltration (P < .01). The mean estimated blood loss was 27.39 ml (SD = 11.44) and the mean duration of post-surgery hospital stay was 1 day (SD = 1.026). Fifty-six patients (92%) recommended diaphyseal plating of the forearm under WALANT. None of the patients required conversion to general anesthesia and had any adverse events or infection during 6 months follow up. Conclusions: Diaphyseal plating of the forearm under WALANT is a feasible alternative anesthesia technique and is well tolerated by patients. Type of study/level of evidence: Therapeutic III.

Outcomes of surgery for infective endocarditis in children: A 30-year experience.

BACKGROUND: Infective endocarditis (IE) is rare in children. Limited data have been reported on long-term outcomes of children who undergo surgery for IE. METHODS: Data were retrospectively obtained from medical records for all children who underwent surgery for IE. RESULTS: Between 1987 and 2017, 138 children with IE required surgery (mean age, 8.3 ± 6.5 years). The majority of children (80.4% [111 out of 138]) had underlying cardiac structural anomalies. Prior heart surgery was performed in 50.7% of patients (70 out of 138), including 19.6% (27 out of 138) who had valve replacement. Operative mortality was 5.8% (8 out of 138). Mean follow-up time was 9.7 ± 7.6 years. Long-term survival at 5 and 25 years was 91.5% (95% confidence interval, 85.1%-95.2%) and 79.1% (95% confidence interval, 66.3%-87.5%), respectively. Risk factors associated with death were: age (hazard ratio [HR], 0.88; P = .015), prosthetic valve IE (HR, 3.86; P = .02), coagulase-negative staphylococci (HR, 4.52; P = .015), increased duration of preoperative antibiotic therapy (HR, 1.02; P = .009), shock (HR, 3.68; P = .028), and aortic valve replacement (HR, 3.22; P = .044). In patients with left-sided IE, risk factors independently associated with death were heart failure (HR, 18.8; P = .025) and vegetation size adjusted to body surface area (HR, 1.06; P = .008). Freedom from recurrent endocarditis was 94.7% (95% confidence interval, 87.7%-97.8%) at 25 years. CONCLUSIONS: Children undergoing surgery for IE had good long-term survival and recurrence of IE was uncommon. Surgery during the active phase of endocarditis did not increase risk of mortality or reoperation. In patients with left-sided IE, vegetation size adjusted for patient body surface area was identified as a risk factor for death, and a useful indicator of prognosis.

Long-Term Outcome After Pulmonary Artery Banding in Children With Atrioventricular Septal Defects.

BACKGROUND: Patients with atrioventricular septal defect (AVSD) may require pulmonary artery banding (PAB), either as a part of a staged univentricular palliation or to allow delayed biventricular repair in patients presenting with early heart failure. The long-term outcomes of PAB in children with AVSD have not been previously reported. METHODS: All children with AVSD who underwent PAB at a single institution were included in the study. Data were obtained from medical records and correspondence with general practitioners and cardiologists. RESULTS: A total of 68 patients with complete AVSD underwent PAB, of whom 58.8% of patients (40 of 68) had balanced AVSD (bAVSD) and underwent PAB with intent to subsequently perform biventricular repair. The remaining 41.2% of patients (28 of 68) had unbalanced AVSD (uAVSD) and underwent PAB as part of staged univentricular repair. PAB was not associated with a short-term increase in atrioventricular valve (AVV) regurgitation (p = 0.24). In patients with bAVSD, 83.8% (95% confidence interval [CI]: 67.4% to 92.4%) achieved biventricular repair. Survival was 73.4% (95% CI: 54.3% to 85.5%) and freedom from left AVV operation was 60.0% (95% CI: 36.1% to 77.4%) at 20 years of follow-up. In patients with uAVSD, 61.9% (95% CI: 40.5% to 77.5%) had achieved Fontan completion at 10 years of follow-up. Survival was 60.9% (95% CI: 36.2% to 78.5%) and freedom from AVV operation was 78.6% (95% CI: 55.5% to 90.6%) at 20 years. CONCLUSIONS: PAB can be used in patients with AVSD without compromising AVV function. Most patients with bAVSD progress to biventricular repair, albeit with a high rate of AVV reoperation. Patients with uAVSD who undergo PAB have similar outcomes to the overall uAVSD population.
