Erector spinae plane block versus its combination with superficial parasternal intercostal plane block for postoperative pain after cardiac surgery: a prospective, randomized, double-blind study.

BACKGROUND: We aimed to compare the effectiveness of bilateral erector spinae plane (ESP) block and superficial parasternal intercostal plane (S-PIP) + ESP block in acute post-sternotomy pain following cardiac surgery. METHODS: Forty-seven patients aged between 18 and 80 years of age with American Society of Anesthesiologists class II-III due to undergo median sternotomy for cardiac surgery were included in this prospective, randomized, double-blinded study. Following randomization into two groups, one group received bilateral ultrasound-guided ESP and the other S-PIP plus ESP block. Morphine consumption within the first 24 h after surgery was the primary outcome of the study while NRS scores at rest, NRS scores when coughing, time taken until extubation, use of rescue analgesic, presence of nausea/vomiting, length of hospital and intensive care unit (ICU) stay, and patient satisfaction were secondary outcome measures. RESULTS: Morphine use up to 24 h following surgery was statistically significantly different between the ESP block and ESP + S-PIP block groups (18.63 ± 6.60 [15.84-21.41] mg/24 h vs 14.41 ± 5.38 [12.08-16.74] mg/24 h, p = 0.021). The ESP + S-PIP block group had considerably reduced pain scores compared to the ESP block group across all time points. Rescue analgesics were required in 21 (87.5%) patients in the ESP block group and seven (30.4%) in the ESP + S-PIP group (p < 0.001). PONV, length of stay in the ICU and hospital, and time to extubation were similar between groups. CONCLUSIONS: In open cardiac surgery, the combination of ESP and S-PIP blocks lowers pain scores and postoperative morphine requirement of patients.

Comparison of Ultrasound-Guided Pecto-intercostal Fascial Block and Transversus Thoracic Muscle Plane Block for Acute Poststernotomy Pain Management After Cardiac Surgery: A Prospective, Randomized, Double-Blind Pilot Study.

OBJECTIVE: The objective of the present study was to evaluate morphine consumption and pain scores 24 hours postoperatively to compare the effects of a bilateral pectointercostal fascial block (PIFB) with those of a transversus thoracic muscle plane block (TTMPB) on acute poststernotomy pain in cardiac surgery patients who have undergone median sternotomy. DESIGN: Prospective, randomized, double-blinded. SETTING: The operating room, intensive care unit, and patient ward at a university hospital. PARTICIPANTS: Thirty-nine American Society of Anesthesiologists II-to-III patients aged 18- to-80 years, scheduled for elective cardiac surgery via median sternotomy. INTERVENTIONS: Patients randomly were allocated to groups scheduled to receive bilateral ultrasound-guided PIFB or TTMPB. MEASUREMENTS AND MAIN RESULTS: The primary outcome was postoperative morphine use within the first 24 hours. Secondary outcomes were the numerical pain rating scale (NRS) scores at rest and during coughing, time of first analgesic demand from the patient-controlled analgesia (PCA) device, and rescue analgesia use. The nausea/vomiting scores, time to extubation, length of stays in intensive care and the hospital, patient satisfaction scores, and complications were also recorded. The first 24-hour morphine use did not significantly differ between the PIFB and TTMPB groups (mean ± standard deviation [95% CI], 13.89 ± 6.80 [10.83-16.95] mg/24 h and 15.08 ± 7.42 [11.83-18.33] mg/24 h, respectively, p = 0.608). No significant difference between the two groups in the NRS scores at rest and during coughing was observed; the groups had similar requirements for rescue analgesia in the first 24 hours (n [%], three [15.8] and seven [35], p = 0.273, respectively). The time from PCA to the first analgesia request was longer in the PIFB than in the TTMPB group (median [interquartile range], 660 [540-900] minutes, and 240 [161-525] minutes, respectively, p = 0.002). CONCLUSIONS: PIFB and TTMPB showed similar effectiveness for morphine consumption within 24 hours postoperatively and in pain scores in cardiac surgery patients.

External compression of left main bronchus by a large patent ductus arteriosus: a case report.

In neonates and infants, the trachea and main bronchus may be compressed by adjacent cardiovascular structures. Compression of the main bronchi by the patent ductus arteriosus is rare and causes a variety of respiratory problems. Surgical closure of the patent ductus arteriosus that compresses the main bronchus as soon as possible is an effective treatment option. Rapid clinical recovery is expected after surgical closure of the patent ductus arteriosus. We present a case of patent ductus arteriosus which caused obstruction of the left main bronchus.

Ligation of left pulmonary artery instead of patent ductus arteriosus.

Ductus arteriosus is an essential component of fetal circulation. Due to occurring changes in the cardiopulmonary system physiology after birth, ductus arteriosus closes. Patent ductus arteriosus can be closed by medical or invasive (percutaneous or surgical) treatment methods. Percutaneous or surgical closure of patent ductus arteriosus can be performed for the cases that medical closure failed. Surgical treatment is often preferred method for closure of patent ductus arteriosus in the neonatal period. The most common surgical complications are pneumothorax, recurrent laryngeal nerve injury, bleeding, and recanalisation. A very rare surgical complication is left pulmonary artery ligation that has been presented in a few cases in the literature. Echocardiography control should be performed in the early post-operative period, especially in patients with clinical suspicion. If reoperation is required, it should never be delayed. We report a newborn patient whose left pulmonary artery ligated accidentally during patent ductus arteriosus closure surgery and surgical correction of this complication at the early post-operative period.

Pre-operative predictors of mortality in ruptured abdominal aortic aneurysms: is the Harborview Medical Center mortality risk score enough?

BACKGROUND: We aimed to evaluate the reliability of the Harborview Medical Center (HMC) mortality risk scoring system in predicting post-operative in-hospital mortality after open repair (OR) of a ruptured abdominal aortic aneurysm (rAAA) and to inves-tigate the presence of other possible mortality risk factors. METHODS: Patients who underwent OR for rAAA between January 01, 2004, and December 31, 2021, were retrospectively included in this single-center cohort study. The 30-day hospital mortality risk was calculated using the HMC risk scoring system. We as-sessed the relationship between mortality and other perioperative variables. Logistic regression analysis was performed to determine the factors affecting mortality. Receiver operating characteristic curve analysis was utilized to obtain the predictive value of the HMC mortality risk score. RESULTS: A total of 91 patients were included in this study. A statistically significant difference existed between the patients who survived and those who died. Univariate logistic regression analysis of the pre-operative patient data revealed that the hematocrit, lactate, shock index values, admission type, loss of consciousness, and HMC risk score significantly affected post-operative mortal-ity. However, in the multivariate logistic regression analysis, only the HMC risk score was associated with post-operative mortality (P<0.001). The HMC risk score could predict 30-day mortality, with an AUC of 0.912 for all patients. CONCLUSION: Our study showed that the HMC risk score could reliably predict in-hospital mortality, but it did not reveal any other parameters that further increased the reliability of this scoring system without compromising on its straightforward and practical calculation.

Incidence of postoperative acute renal failure among violence-related cardiovascular trauma patients: a review of our experience in 117 cases.

BACKGROUND: The purpose of this retrospective study was to determine the incidence of renal failure and hemodialysis (HD) in postoperative period after cardiovascular surgery associated with trauma. METHODS: One hundred and seventeen cases of violence-related cardiovascular trauma patients had emergent surgery between 1996 and 2009. Cases were reviewed in three main groups: Cardiac trauma in 11 patients (Group A), vascular trauma in 78 patients (Group B), and cardiovascular trauma in 28 patients (Group C). Postoperative incidence of HD requirements with acute renal failure (ARF) was investigated in these groups of patients postoperatively. RESULTS: Multiorgan deficiency developed in 10 patients from Group A, in 45 patients from Group B, and in 26 patients from Group C. Overall mortality was 81 cases in 117 patients. Total hospitalization periods were 21 +/- 2, 17 +/- 3, and 27 +/- 1 days for Group A, Group B, and Group C, respectively. HD administrations were indicated in 3 patients in Group A, 41 patients in Group B, and 9 patients in Group C. No statistically significant difference presented in any study parameter between groups. CONCLUSIONS: Cardiovascular trauma is a common reason for emergent cardiovascular surgery. Postoperative renal failure occurs among these patients in a wide percentage. We strongly advocate a close and detailed follow-up of renal functions in these patients during the hospitalization period and immediate HD at indication.

Influence of Bentall Procedure on Left Ventricular Function.

OBJECTIVE: To evaluate the influence of Bentall procedure on left ventricular function and condition on long-term follow-up. METHODS: Seventy-three consecutive patients who underwent an aortic root and ascending aorta replacement with composite valve button Bentall or flanged Bentall technique, from January 2007 to November 2018, were included in this retrospective study. RESULTS: Postoperative left ventricular ejection fraction significantly increased (52.14±11.38 vs. 56.79±11.36; P=0.041), left ventricular end-systolic diameter significantly reduced (38.25±9.31 mm vs. 34.17±9.15 mm; P=0.027), left ventricular end-diastolic diameter significantly reduced (56.42±9.72 mm vs. 51.58±9.03 mm; P=0.01), and left atrial diameter significantly reduced (45.33±12.77 mm vs. 39.25±12.41 mm; P=0.01), compared to preoperative values. Our long-term survival results are comparable with previous studies in which survival rates in 5 years and 10 years were 83.5% and 69.8%, respectively. In comparing patients according to their New York Heart Association (NYHA) functional class, it was shown that their postoperative functional capacity was improved during the follow-up period (2.1±0.56 vs. 1.2±0.42; P=0.001). CONCLUSION: The Bentall procedure significantly improved the left ventricular systolic function and condition and decreased the left ventricular end-systolic and end-diastolic diameters and the left atrial diameter on long-term follow-up, based on the transthoracic echocardiography. Bentall procedure can be performed with acceptable mortality and morbidity rates on long-term follow-up.

Relationship of Inter-Arm Systolic Blood Pressure Difference with Subclavian Artery Stenosis and Vertebral Artery Stenosis in Patients Undergoing Carotid Endarterectomy.

INTRODUCTION: The aim of this study was to examine the association of inter-arm systolic blood pressure difference (IASBPD) with carotid artery stenosis, subclavian artery stenosis and vertebral artery stenosis in patients who underwent carotid endarterectomy. METHODS: A total of 141 patients (29 females, 112 males; mean age 71.2±10.4 years; range 47 to 92 years) who underwent carotid endarterectomy between September 2010 and December 2017 were retrospectively evaluated. We classified patients into four groups according to the IASBPD ˂ 10 mmHg, ≥ 10 mm Hg, ≥ 20 mmHg and ≥ 30 mmHg. The stenosis of both subclavian and vertebral arteries was considered as ≥ 50%. RESULTS: Of the 141 patients, 44 (31.2%) had ≥ 10 mmHg, 29 (20.5%) had ≥ 20 mmHg and 4 (2.8%) had ≥ 30 mmHg of IASBPD. 26 patients (18.4%) were diagnosed with significant subclavian artery stenosis and 18 (69.2%) of them had more than 20 mmHg of IASBPD. Of the 29 patients with IASBPD ≥ 20 mmHg, 19 patients (65.5%) had a significant subclavian artery stenosis. We found a significant correlation between preoperative symptoms and subclavian artery stenosis (P=0.018) and overall perioperative stroke was seen more frequently in patients with subclavian artery stenosis (P=0.041). A significant positive correlation was observed between vertebral artery stenosis and subclavian artery stenosis (P=0.01). CONCLUSION: Patients who were diagnosed with both subclavian artery stenosis and IASBPD (≥ 20 mmHg) had a higher risk of postoperative stroke and death, had higher total cholesterol, LDL-C, blood creatinine level, and were more symptomatic.
