BACKGROUND CONTEXT: Postoperative pain control following spine surgery can be difficult. The Enhanced Recovery After Surgery (ERAS) programs use multimodal approaches to manage postoperative pain. While an erector spinae plane block (ESPB) is commonly utilized, the ideal distance for injection from the incision, referred to as the ES (ESPB to mid-surgical level) distance, remains undetermined. PURPOSE: We evaluated the impact of varying ES distances for ESPB on Numerical Rating Scale (NRS) measures of postoperative pain within the ERAS protocol...

Measurements of common carotid artery diameter, velocity time integral, and systolic flow time (FT) were performed before and after a fluid challenge...

Hypotension induced by general anesthesia is associated with postoperative complications, increased mortality, and morbidity, particularly elderly patients. The aim of this study was to investigate the effectiveness of corrected carotid artery flow time (FTc) for predicting hypotension following anesthesia induction in patients over 65 years old. After faculty ethical committee approval and written informed consent, 138 patients (65 years and older, ASA physical status I-III) who scheduled for elective surgery were included in this study...

Sternal wound complications following sternotomy need a multidisciplinary approach in high-risk postoperative cardiac surgical patients. Poorly controlled pain during surgical management of such wounds increases cardiovascular stress and respiratory complications. Multimodal analgesia including intravenous opioids, non-opioid analgesics, and regional anesthesia techniques, like central neuraxial blocks and fascial plane blocks, have been described. Pecto-intercostal fascial plane block (PIFB), a novel technique, has been effectively used in patients undergoing cardiac surgery...

The elephant trunk procedure, an endovascular strategy for retrograde type A acute aortic dissection, is associated with several complications, hemolytic anemia being a rare one. We performed endovascular stent-graft insertion in a patient who developed hemolytic anemia. Transesophageal echocardiography (TEE) detected turbulent jet flow and stenosis position, which was not detected by angiography and intravascular ultrasound (IVUS). This imaging technique proved effective for malperfusion diagnosis and enabled us to confirm its resolution after the endovascular procedure...

This retrospective study included 216 patients undergoing RARC surgery From January 1, 2022 to December 30, 2023, and propensity score adjustment analysis was applied. The study compares a control group receiving traditional nursing and an observation group receiving RARC-ERAS nursing program...

BACKGROUND: Pulmonary aspiration syndrome remains a significant complication of general anesthesia, particularly in unfasted patients. Gastric point-of-care ultrasound (POCUS) allows for both qualitative and quantitative assessment of gastric content, providing a safe and reliable method to assess gastric emptying and reduce the risk of aspiration during general anesthesia. METHODS: The survey was distributed to Belgian certified anesthesiologists and trainees between April 2020 and June 2021...

BACKGROUND: Diaphyseal forearm fractures are common traumatic injuries among children. There has been much debate on the use of intramedullary nailing (IMN) or plate fixation in the adolescent population (10-16 years of age). Furthermore, as ultrasound technology has advanced, the safety and efficacy of ultrasound-guided axillary brachial plexus block for children has dramatically improved. Therefore, anesthesia options for adolescent patients have increased in recent years. This study aimed to investigate recent surgical and regional anesthesia trends of diaphyseal forearm fractures in patients 10 to 16 years of age in Japan through a multicenter epidemiological survey from 2011 to 2020...

BACKGROUND: We have developed a new approach for peripherally inserted central catheter (PICC) insertion that we think has several advantages, including ease of insertion, access to a larger vein and patient comfort. METHODS: In this case series report, the first 19 cases were audited. RESULTS: All PICCs were inserted without complications; 17 on the first attempt. CONCLUSION: We conclude that the novel approach to the axillary vein for PICC insertion is feasible and appears to be safe when performed by an experienced operator...

OBJECTIVE: To investigate the effect of ultrasound-guided stellate ganglion block (SGB) on cerebral oxygen metabolism and serum S100B during carotid endarterectomy (CEA).

KEY CLINICAL MESSAGE: Incidence of bilateral inguinal hernia encompassing bilateral ovaries in adult female is very thin and concomitant association with Mayer-Rokitansky-Küster-Hauser syndrome is out of ordinary. Along with surgical management of hernia, these females need multidisciplinary slant to manage gynecological, social, and emotional issues. ABSTRACT: In mature females, bilateral ovarian inguinal hernias are a rarity. In this situation, ultrasonography is the basic adjunct to confirm the diagnosis...

BACKGROUND AND OBJECTIVES: The subclavian vein is frequently cannulated using ultrasound. There are two techniques of subclavian vein catheterization (SVC): Supraclavicular (SC) and infraclavicular (IC). Though the IC route is often preferred, the SC approach offers several distinct advantages. This study was planned to compare the technique of SVC using SC and IC approaches in terms of catheterization technique and complications in elective surgeries in adults. METHODS: Sixty American Society of Anesthesiologists (ASA) 1, 2, or 3 adult patients posted for elective surgeries under general anesthesia were recruited...

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is commonly associated with moderate-to-severe postoperative pain. Notably, various pain control strategies, a femoral nerve block (FNB) with a lateral femoral cutaneous nerve block (LFCNB), adductor canal block (ACB) with LFCNB, or periarticular cocktail injection (PI), have been investigated. However, no studies compare the effects of FNB with LFCNB, ACB with LFCNB, and PI for pain control after ACL reconstruction. This study aimed to evaluate the impact of FNB with LFCNB, ACB with LFCNB, and PI for pain relief in the early postoperative period after ACL reconstruction...
