Elective, Non-urgent Procedures and Aesthetic Surgery in the Wake of SARS-COVID-19: Considerations Regarding Safety, Feasibility and Impact on Clinical Management.

BACKGROUND: The worldwide spread of a novel coronavirus disease (COVID-19) has led to a near total stop of non-urgent, elective surgeries across all specialties in most affected countries. In the field of aesthetic surgery, the self-imposed moratorium for all aesthetic surgery procedures recommended by most international scientific societies has been adopted by many surgeons worldwide and resulted in a huge socioeconomic impact for most private practices and clinics. An important question still unanswered in most countries is when and how should elective/aesthetic procedures be scheduled again and what kind of organizational changes are necessary to protect patients and healthcare workers when clinics and practices reopen. Defining manageable, evidence-based protocols for testing, surgical/procedural risk mitigation and clinical flow management/contamination management will be paramount for the safety of non-urgent surgical procedures. METHODS: We conducted a MEDLINE/PubMed research for all available publications on COVID-19 and surgery and COVID-19 and anesthesia. Articles and referenced literature describing possible procedural impact factors leading to exacerbation of the clinical evolution of COVID-19-positive patients were identified to perform risk stratification for elective surgery. Based on these impact factors, considerations for patient selection, choice of procedural complexity, duration of procedure, type of anesthesia, etc., are discussed in this article and translated into algorithms for surgical/anesthesia risk management and clinical management. Current recommendations and published protocols on contamination control, avoidance of cross-contamination and procedural patient flow are reviewed. A COVID-19 testing guideline protocol for patients planning to undergo elective aesthetic surgery is presented and recommendations are made regarding adaptation of current patient information/informed consent forms and patient health questionnaires. CONCLUSION: The COVID-19 crisis has led to unprecedented challenges in the acute management of the crisis, and the wave only recently seems to flatten out in some countries. The adaptation of surgical and procedural steps for a risk-minimizing management of potential COVID-19-positive patients seeking to undergo elective aesthetic procedures in the wake of that wave will present the next big challenge for the aesthetic surgery community. We propose a clinical algorithm to enhance patient safety in elective surgery in the context of COVID-19 and to minimize cross-contamination between healthcare workers and patients. New evidence-based guidelines regarding surgical risk stratification, testing, and clinical flow management/contamination management are proposed. We believe that only the continuous development and broad implementation of guidelines like the ones proposed in this paper will allow an early reintegration of all aesthetic procedures into the scope of surgical care currently performed and to prepare the elective surgical specialties better for a possible second wave of the pandemic.

Modified Suzuki frame for the treatment of difficult Rolando fractures.

Fifteen consecutive patients with severely comminuted Rolando fractures were treated by closed reduction and fixation with a modified Suzuki frame without rubber bands, followed by immediate mobilization. All the fractures healed within 5 weeks. At 3 months, no rotational deformity was observed. The Kapandji score was equal that of the contralateral thumb in eight cases. No residual pain was recorded. Grip strength was 78% and pinch strength was 78% of the contralateral hand. One patient needed the frame tension modified. One patient developed a sensory deficit in the area of the superficial branch of the radial nerve that resolved spontaneously in 3 months. One patient healed with a 2-mm articular step-off, but the clinical outcome was good. Our retrospective study suggests that the small modification we made to the Suzuki frame provides a relatively simple and minimally invasive technique for the treatment of comminuted Rolando fractures.

Long-term clinical outcome after epineural coaptation of digital nerves.

UNLABELLED: This study evaluates the long-term clinical outcome and complication rate after digital nerve repair in adults and aims to identify possible prognostic factors of sensory recovery. End-to-end epineural coaptation was performed under magnification. A total of 93 coapted digital nerves were clinically evaluated with a mean follow-up of 3.5 years (range 1-6 years). The mean two-point discrimination was 10.6 mm (versus 4.4 mm for the contralateral side). Cutaneous pressure threshold tested with Semmes-Weinstein monofilaments showed a mean value of 2.7 (versus 2.2 for the contralateral side). Only 2% of our patients developed painful neuromas. None of our patients recovered normal functional sensibility, however, recovery of protective sensation contributed to a high reported level of satisfaction. No correlation was observed between the sensory outcome and age, smoking, mechanism of injury, lesion to or anastomosis of a digital artery, or time of immobilization. The only identified predictor of the result was the surgeon's level of experience. This highlights the importance of adequate training and practice in the surgical repair of smaller peripheral nerves. LEVEL OF EVIDENCE: IV.

Replantation by palmar arteriovenous anastomosis in complex finger amputations.

Digital replantation is a well-established and increasingly common procedure in specialized hand surgery units worldwide. Replantation after complex trauma is often challenging due to severely injured, small-diameter vessels, especially at the distal level. Digit salvage by arteriovenous anastomosis has been inadequately described in the literature for such cases. The objective of this study was to evaluate the outcomes and complications of arteriovenous digital replantation in complex amputations. We reviewed five cases of digital replantation using a single palmar afferent arteriovenous anastomosis and drainage via a dorsal vein. The postoperative protocol followed our standard replantation protocol. All digits survived with no revision procedures. No major complications were observed. One digit developed partial epidermolysis and one thumb developed marginal skin necrosis, both treated conservatively. The color of the replanted digits was not a reliable monitoring parameter but capillary refill was consistently visible. Microangiography performed four months after surgery demonstrated good digit perfusion. Our results support palmar arteriovenous anastomosis as a reliable alternative in digital replantation if distal arteries are unavailable for anastomosis. The results also suggest that this digit salvage procedure can be carried out at a more proximal level than previously reported.

Primary functional and aesthetic restoration of the fingernail in distal fingertip amputations with the eponychial flap.

Fingertip injuries often result in fingernail defects. Reconstruction of this structure is important for adequate functional and aesthetic results. This study evaluates the eponychial flap reconstruction technique in 45 fingertip amputations with loss of more than half the fingernail. In 33 cases the procedure was performed in combination with a palmar island flap for pulp reconstruction. Average follow up was 5 months. All eponychial flaps healed uneventfully. In 44 cases, the pulp volume was restored without nail growth disturbance. Five complications (9%) were observed (pain, soft nail, and nail deformity). Only one hook nail deformity required reoperation. All patients were satisfied with the aesthetic and functional outcome. We found eponychial flap fingernail reconstruction effective even for injuries proximal to the lunula and have extended the indication for this technique to very proximal fingernail defects. Eponychial flap reconstruction is a simple, safe, and time-effective technique without donor site morbidity. Simultaneous reconstruction of dorsal and palmar injuries should both be performed primarily resulting in the restoration of a satisfying fingertip.

Influence of temperature management on neurocognitive function in biological aortic valve replacement. A prospective randomized trial.

AIM: Aim of this study was to elucidate if postoperative neurocognitive function after biological aortic valve replacement (AVR) can be influenced by temperature management during cardiopulmonary bypass (CPB). METHODS: In this prospective randomized study, we measured the effect of mild hypothermic (32 °C, N.=30) vs. normothermic (37 °C, N.=30) CPB on neurocognitive function. All patients underwent elective isolated biological AVR (mean age 67 ± 8 years, mean additional EuroSCORE 5.6 ± 2.4). Neurocognitive function was objectively measured by means of objective P300 auditory-evoked potentials before surgery, one week and four months after surgery. Clinical data and outcome were monitored. RESULTS: P300 evoked potentials were comparable between patients operated with mild hypothermic (370 ± 30 ms) and normothermic CPB (373 ± 32 ms) before surgery (P=0.85). P300 peak latencies were prolonged (=impaired) in patients operated with normothermic (402 ± 29, P<0.0001) as well as with mild hypothermic CPB (405 ± 30 ms, P<0.0001) one week after surgery. Even four months after surgery, still impairment of P300 peak latencies could be documented in either patients operated with normothermic (394 ± 28 ms) and mild hypothermic CPB (400 ± 33 ms,) in repeated measures analysis of variance (P=0.042). Group comparison revealed no difference between patients operated with normothermic and mild hypothermic CPB at one week (P=0.54) and four months (P=0.67) after surgery. Clinical data as well as postoperative adverse events were comparable between the two groups. CONCLUSION: Normothermic temperature management during CPB is non-inferior to hypothermic in means of neuroprotection. Since patients after biological aortic valve replacement show a subclinical but measurable cognitive deficit up to four months after surgery, other factors have to be addressed to add further benefit to the extremely good results of open biological AVR.
