Which ultrasound-guided parasternal intercostal nerve block for post-sternotomy pain? Results from a prospective observational study.

BACKGROUND: Parasternal intercostal blocks (PSB) have been proposed for postoperative analgesia in patients undergoing median sternotomy. PSB can be achieved using two different approaches, the superficial parasternal intercostal plane block (SPIP) and deep parasternal intercostal plane block (DPIP) respectively. METHODS: We designed the present prospective, observational cohort study to compare the analgesic efficacy of the two approaches. Cardiac surgical patients who underwent full sternotomy from January to September 2022 were enrolled and divided into three groups, according to pain control strategy: morphine, SPIP, and DPIP group. Primary outcomes were was postoperative pain evaluated as absolute value of NRS at 12 h. Secondary outcomes were the NRS at 24 and 48 h, the need for salvage analgesia (both opioids and NSAIDs), incidence of postoperative nausea and vomiting, time to extubation, mechanical ventilation duration, and bowel disfunction. RESULTS: Ninety-six were enrolled. There was no significant difference in terms of median Numeric Pain Rating Scale at 24 h and at 48 h between the study groups. Total postoperative morphine consumption was 1.00 (0.00-3.00), 2.00 (0.00-5.50), and 15.60 mg (9.60-30.00) in the SPIP, DPIP, and morphine group, respectively (SPIP and DPIP vs morphine: p < 0.001). Metoclopramide consumption was lower in SPIP and DPIP group compared with morphine group (p = 0.01). There was no difference in terms of duration of mechanical ventilation and of bowel activity between the study groups. Two pneumothorax occurred in the DPIP group. CONCLUSIONS: Both SPIP and DPIP seem able to guarantee an effective pain management in the postoperative phase of cardiac surgeries via full median sternotomy while ensuring a reduced consumption of opioids and antiemetic drugs.

The Burden of Carbapenem-Resistant Acinetobacter baumannii in ICU COVID-19 Patients: A Regional Experience.

Since the beginning of the COVID-19 pandemic, the impact of superinfections in intensive care units (ICUs) has progressively increased, especially carbapenem-resistant Acinetobacter baumannii (CR-Ab). This observational, multicenter, retrospective study was designed to investigate the characteristics of COVID-19 ICU patients developing CR-Ab colonization/infection during an ICU stay and evaluate mortality risk factors in a regional ICU network. A total of 913 COVID-19 patients were admitted to the participating ICUs; 19% became positive for CR-Ab, either colonization or infection (n = 176). The ICU mortality rate in CR-Ab patients was 64.7%. On average, patients developed colonization or infection within 10 ± 8.4 days from ICU admission. Scores of SAPS II and SOFA were significantly higher in the deceased patients (43.8 ± 13.5, p = 0.006 and 9.5 ± 3.6, p < 0.001, respectively). The mortality rate was significantly higher in patients with extracorporeal membrane oxygenation (12; 7%, p = 0.03), septic shock (61; 35%, p < 0.001), and in elders (66 ± 10, p < 0.001). Among the 176 patients, 129 (73%) had invasive infection with CR-Ab: 105 (60.7%) Ventilator-Associated Pneumonia (VAP), and 46 (26.6%) Bloodstream Infections (BSIs). In 22 cases (6.5%), VAP was associated with concomitant BSI. Colonization was reported in 165 patients (93.7%). Mortality was significantly higher in patients with VAP (p = 0.009). Colonized patients who did not develop invasive infections had a higher survival rate (p < 0.001). Being colonized by CR-Ab was associated with a higher risk of developing invasive infections (p < 0.001). In a multivariate analysis, risk factors significantly associated with mortality were age (OR = 1.070; 95% CI (1.028−1.115) p = 0.001) and CR-Ab colonization (OR = 5.463 IC95% 1.572−18.988, p = 0.008). Constant infection-control measures are necessary to stop the spread of A. baumannii in the hospital environment, especially at this time of the SARS-CoV-2 pandemic, with active surveillance cultures and the efficient performance of a multidisciplinary team.

Surgical left ventricle remodeling to treat functional mitral valve regurgitation.

A left ventricular aneurysm complicates an acute myocardial infarction in 4-20% of patients. The loss of the physiological geometry of the ventricle can lead to a dislocation of the papillary muscles with subsequential mitral valve regurgitation. The goal of this case report is to demonstrate that a proper operation to restore the left ventricular anatomy can be a feasible procedure to correct functional mitral regurgitation.

Another step in transcatheter aortic valve implantation: A challenging transcatheter aortic valve implantation procedure in patient with severe peripheral arterial disease.

Approximately 25% of patients undergoing transcatheter aortic valve implantation presents significant peripheral arterial disease. The purpose of this case report was to present a feasible approach for transcatheter heart valve in a patient with peripheral arterial disease where the presence of a subclavian stent jutting in the aortic arch made the delivery system passage a challenging procedure.

Matryoshka procedure for Valve-in-Valve TAVI failure.

Valve-in-valve transcatheter valve implantation (ViV-TAVI) procedures for deteriorated bioprosthesis are an established therapeutic option for high-risk patients. The presence of the fixed sewing ring of the bioprosthesis can hamper appropriate expansion of the TAVI. We present a case of a ViViV-TAVI, as a salvage procedure for acute ViV-TAVI failure.

Extracorporeal life support programme for out-of-hospital cardiac arrest during competitive sport events: the experience of the Volleyball Men's World Championship Final Six in Turin (Italy).

The high incidence of out-of-hospital cardiac arrest refractory to standard resuscitation protocols, despite precompetitive screening, demonstrated the need for a prehospital team to provide an effective system for life support and resuscitation at the Volleyball Men's World Championship. The evolution of mechanical circulatory support suggests that current advanced cardiovascular life support protocols no longer represent the highest standard of care at competitive sporting events with large spectator numbers. Extracorporeal life support (ECLS) improves resuscitation strategies and offers a rescue therapy for refractory cardiac arrest that can no longer be ignored. We present our operational experience of an out-of-hospital ECLS cardiopulmonary resuscitation team at an international sporting event.

[Hospital mortality at a cardiosurgical unit in Torino: international comparisons and time trend]. / Mortalità ospedaliera in una unità di cardiochirurgia di Torino: confronti internazionali e andamento temporale.

OBJECTIVE: To compare hospital mortality in a cardiac surgery unit with external data and to assess changes in time (patients undergoing surgery in two different periods). MATERIALS AND METHODS: Data on risk factors for hospital mortality were collected from clinical records (retrospectively for the first period and prospectively for the second) for all patients undergoing open heart surgery at the Heart Surgery Unit of the University of Turin (Italy) during 1991 and 1995 (n = 1794) and 1999 (n = 892). Comparisons of in-hospital mortality, expressed as Standardized Mortality Ratios (SMR), were adjusted for risk factors defined according to EuroSCORE (European System for Cardiac Operative Risk Evaluation). RESULTS: In the first and second period, complete information on all the 17 EuroSCORE items was available for 58.3% and 89.6% patients respectively. After exclusion of patients with one or more missing data, observed and expected numbers of death were found to be very similar, with SMRs ranging between 0.82 (isolated bypass in the second period) and 1.06 ("other" surgery in the first period). Mortality was higher among patients with missing data, but at least in 1999 the latter had a limited impact on the overall estimates. Compared to the first period, mortality was reduced during 1999 (from 5.9% to 5.4%), in particular for isolated bypass (from 4.4% to 3.4%). CONCLUSIONS: In the unit under investigation, hospital mortality following heart surgery was similar to that predicted from EuroSCORE and seemed to be lower in 1999 than in 1991-95, particularly for isolated bypass. Incompleteness of data on individual risk factors may have been a source of bias, especially when data were collected retrospectively.
