Tocilizumab use during Covid-19 should alert an orthopaedic surgeon for the surgical management of arthroplasty patients: A narrative review

The crisis of Covid-19 has shaken the world healthcare systems. The intensive care resources to manage the medical conditions associated with Covid-19 are consistently found to be inadequate with exploration and implementation of newer treatment avenues for an early recovery. Presently, the use of Tocilizumab (TCZ) in severe to critical affection of Covid-19 is being practiced as an off-label therapy. A narrative review of present knowledge regarding TCZ pharmacology, indications of its use, and potential side effects with clinical implications for an orthopedic surgeon is presented. The article discusses the clinicopathological factors required to be monitored during the perioperative management of an orthopedic patient who may have received TCZ for Covid-19 related illness. The implications of its usage should alert the orthopaedic surgeons for future management of their arthritic surgical patients. The commonly associated side effects and complications in the post-operative phase following an arthroplasty or any orthopaedic surgery are an area of concern and considerable uncertainty. In the post-Covid-19 recovery phase, when surgeons need to plan a surgical intervention then a thorough evaluation of their Covid-19 medical management history may be warranted. Practical guidelines for the management of arthritic surgical patients have been postulated. With an unregulated increased usage of TCZ during Covid-19 management, an orthopaedic surgeon should worry and needs to be aware of the possible consequences in the perioperative period for the post-surgery management. Future research to gain more insights will confirm the implied concerns.

Prospective randomized study comparing outcome of myocardial protection with Del-Nido Cardioplegia versus Saint Thomas Cardioplegia in adult cardiac surgical patients

Objectives: To compare the effectiveness of Del-Nido cardioplegia as myocardial protective agent with Saint Thomas cardioplegia in adult cardiac surgical patients. Methods: This prospective randomized study was conducted in cardiac surgery department of Bahawal Victoria hospital Bahawalpur, from October 2020 to March 2021. Eighty adult patients who underwent primary Isolated coronary artery bypass grafting (CABG) or isolated Valve surgery requiring cardiopulmonary bypass were randomly divided into Del Nido (DN, n=40) and Saint Thomas (ST, n=40) groups. Data regarding operative and post-operative variables such as cardiopulmonary bypass (CPB) and aortic cross clamp (AXC) times, inotropic requirements, resumption of sinus rhythm, need for electrical defibrillation, post-operative CKMB, blood requirement and ICU stay were noted. Results: CPB and AXC times were statistically insignificantly different. Resumption of Sinus rhythm was seen significantly in more patients of DN group (95%) than in ST group (72.5%) [p-value 0.05]. Less patients of DN group (5%) were candidates of electrical defibrillation than ST group (17.5%) [p-value <0.001). Post- operative CKMB values were significantly lower in DN group as compared to ST group (30.5±22.6 IU vs 50.5±50.28 IU, p value.008). Blood transfusion was significantly lower in DN group; 50% versus 80% in ST group (p-value 0.005). Ventilation time was significantly less in DN group than ST group (165.95±48.09 minutes versus 165.95±48.09 minutes respectively, p-value 0.03). While ICU stay was also less in DN group; 5.2±0.8 days versus 6.05±1.6 days in ST group (p-value 0.003). Conclusion: Del-Nido cardioplegia is a reliable and better myocardial protective agent than Saint Thomas cardioplegia in adult cardiac surgical procedures. doi: https://doi.org/10.12669/pjms.38.3.4730 How to cite this:Rizvi MFA, Yousuf SMA, Younas A, Baig MAR.

Preoperative anaemia and red blood cell transfusion in patients with aneurysmal subarachnoid and intracerebral haemorrhage – A multicentre subanalysis of the German PBM Network Registry

Purpose Anaemia is common in patients presenting with aneurysmal subarachnoid (aSAH) and intracerebral haemorrhage (ICH). In surgical patients, anaemia was identified as an idenpendent risk factor for postoperative mortality, prolonged hospital length of stay (LOS) and increased risk of red blood cell (RBC) transfusion. This multicentre cohort observation study describes the incidence and effects of preoperative anaemia in this critical patient collective for a 10-year period. Methods This multicentre observational study included adult in-hospital surgical patients diagnosed with aSAH or ICH of 21 German hospitals (discharged from 1 January 2010 until 30 September 2020). Descriptive, univariate and multivariate analyses were performed to investigate the incidence and association of preoperative anaemia with RBC transfusion, in-hospital mortality and postoperative complications in patients with aSAH and ICH. Results A total of n = 9,081 patients were analysed (aSAH n = 5,008; ICH n = 4,073). Preoperative anaemia was present at 28.3% in aSAH and 40.9% in ICH. RBC transfusion rates were 29.9% in aSAH and 29.3% in ICH. Multivariate analysis revealed that preoperative anaemia is associated with a higher risk for RBC transfusion (OR= 3.25 in aSAH, OR = 4.16 in ICH, p < 0.001), for in-hospital mortality (OR= 1.48 in aSAH, OR= 1.53 in ICH, p < 0.001) and for several postoperative complications. Conclusions Preoperative anaemia is associated with increased RBC transfusion rates, in-hospital mortality and postoperative complications in patients with aSAH and ICH.

KIBRA, MTNR1B, and FKBP5 genotypes are associated with decreased odds of incident delirium in elderly post-surgical patients

Despite the association between cognitive impairment and delirium, little is known about whether genetic differences that confer cognitive resilience also confer resistance to delirium. To investigate whether older adults without postoperative delirium, compared with those with postoperative delirium, are more likely to have specific single nucleotide polymorphisms (SNPs) in the FKBP5, KIBRA, KLOTHO, MTNR1B, and SIRT1 genes known to be associated with cognition or delirium. This prospective nested matched exploratory case–control study included 94 older adults who underwent orthopedic surgery and screened for postoperative delirium. Forty-seven subjects had incident delirium, and 47 age-matched controls were not delirious. The primary study outcome was genotype frequency for the five SNPs. Compared with participants with delirium, those without delirium had higher adjusted odds of KIBRA SNP rs17070145 CT/TT [vs. CC; adjusted odds ratio (aOR) 2.80, 95% confidence interval (CI) 1.03, 7.54; p = 0.04] and MTNR1B SNP rs10830963 CG/GG (vs. CC; aOR 4.14, 95% CI 1.36, 12.59; p = 0.01). FKBP5 SNP rs1360780 CT/TT (vs. CC) demonstrated borderline increased adjusted odds of not developing delirium (aOR 2.51, 95% CI 1.00, 7.34; p = 0.05). Our results highlight the relevance of KIBRA, MTNR1B, and FKBP5 in understanding the complex relationship between delirium, cognition, and sleep, which warrant further study in larger, more diverse populations.

Establishment and Application of Pressure Injury Assessment Module in Operating Room Based on Information Management System

A pressure injury is a common and painful health condition, particularly among people who are elderly or surgical patients. In order to explore how to use the information management system to optimize the pressure injury management process of surgical patients, this work establishes an integrated pressure injury management information platform for surgical patients, which can effectively control the key links in the process and realize the multistep full-process monitoring of surgical patients from admission to discharge. A total of 578 patients before the operation of the information platform were selected as the control group (CG), and after the operation of the information platform, 662 cases became the observation group (OG). Various evaluation metrics are employed to evaluate pressure injury in terms of single-pass rate, high-risk pressure injury, transfer skin condition description matching rate, hospital pressure injury incidence, and incidence of pressure injury in surgical patients at various stages. The results showed that the qualified rate of the pressure injury assessment in the OG was 99.2%, the accuracy rate of high-risk pressure injury screening and reporting was 100.0%, and the matching rate of the transfer skin description was 100.0%, which was higher than that of the CG. The integrated pressure injury management information platform for surgical patients based on the information management system realizes the full, continuous, accurate, and dynamic evaluation and monitoring of patients’ skin. Furthermore, it can effectively improve the quality of pressure injury care and facilitate care management.
