spinal anaesthesia

Spinal anesthesia is one of the most widely used techniques in modern anesthesia practice. It involves the injection of local anesthetic drugs into the cerebrospinal fluid (CSF) within the subarachnoid space. The choice of drug, its concentration, and baricity play a crucial role in determining the characteristics of the spinal block and has evolved over the years with continuous advancements in drug formulations and administration methods. Spinal anesthesia with hypobaric drugs represents a valuable technique in the armamentarium of anesthesiologists, offering distinct advantages in terms of targeted action, reduced systemic toxicity, and enhanced hemodynamic stability...

Morgagni hernias are uncommon diaphragmatic defects and are commonly found incidentally as a congenital defect. Acquired Morgagni hernias have been documented in the pediatric population, making them extremely uncommon. Thoracic segmental spinal anesthesia (TSSA) may be used as a successful substitute for general anesthesia, especially in cardiovascularly compromised patients like our patient who had heart failure with reduced ejection fraction (HFrEF), and this is one of the very few documented cases of acquired Morgagni hernia laparoscopic repair surgery done by this anesthesia method...

Combined spinal-epidural anaesthesia is an excellent technique for providing intraoperative and postoperative analgesia in patients undergoing total knee arthroplasty. Epidural catheters threaded through a Tuohy needle with a cephalad needle bevel orientation follow a winding pattern within the epidural space. Caudal or downward migration of an epidural catheter may lead to unsatisfactory anaesthesia and epidural failure. Colour flow Doppler sonography is emerging as an effective technique to determine the epidural catheter tip position...

BACKGROUND AND AIMS: There is limited data on the effects of norepinephrine on neonatal outcomes and maternal complications relative to other vasopressors. The study aimed to compare neonatal outcomes and maternal complications after bolus intravenous doses of phenylephrine and norepinephrine for post-spinal hypotension in elective caesarean section women. METHODS: This randomised study was done on 100 elective caesarean section women under spinal anaesthesia. Block randomisation divided women into two groups to receive intravenous phenylephrine 50 μg bolus (Group A) or norepinephrine 5 μg bolus (Group B) following post-spinal hypotension...

BACKGROUND AND AIMS: Apprehension of pain due to a spinal needle is often a cause of anxiety and refusal. ShotBlocker provides non-painful physical stimulation, inhibiting pain perception. The vapocoolant spray contains ethyl chloride vapours, rapidly raising the skin temperature and hampering the transmission of noxious stimuli. The present study compared the effectiveness of the ShotBlocker device and the vapocoolant spray in reducing spinal needle-associated pain in primigravida women undergoing elective lower-segment caesarean section (LSCS)...

BACKGROUND: Failed spinal anaesthesia causes prolonging of operation time, insufficient analgesia for surgery and needs repeating spinal anaesthesia which in turn causes local anaesthesia toxicity, high spinal and total spinal, and conversion to general anaesthesia. However, the problem remains unexplored in Amhara regional state comprehensive specialized hospitals. OBJECTIVE: To determine incidence and factors associated with failed spinal anaesthesia among patients undergoing surgery in selected Amhara National Regional State comprehensive specialized hospitals, Northwest Ethiopia, 2023...

A woman in her mid-50s, hesitant about general anaesthesia due to a difficult airway, opted for neuraxial anaesthesia for L4 laminectomy with pedicle screw fixation (L3-L5). Preoperatively, she received 150 µg buprenorphine and 1 mg midazolam. In lateral position, a T8-T9 epidural catheter was placed, followed by segmental spinal anaesthesia (2.5 mL 0.5% hyperbaric bupivacaine+30 µg clonidine) at T10-T11. Prone positioning was executed using standard techniques. During the 6-7 hours surgery, three 7 mL epidural top-ups (2% lignocaine epinephrine) were administered at 90 min intervals...

We present the case of a successful application of combined spinal-epidural anesthesia for a geriatric patient undergoing open cancer surgery. The patient, affected by multiple comorbidities, was proposed for an open anterior rectal resection. The implementation of a tailored protocol, incorporating neuraxial techniques such as epidural and spinal anesthesia, facilitated optimal pain management and expedited postoperative recovery improving perioperative outcomes, and highlighting the potential benefits of such strategies in selected cases...

This study investigates the association between postoperative agitated delirium and the risk of dementia in patients who were cognitively intact before undergoing major inpatient surgery. The study included inpatients aged 20 years or older who underwent major surgery requiring general, epidural, or spinal anaesthesia and hospitalization for over one day in Taiwan between 2008 and 2018. Patients were categorized into two groups based on the presence or absence of postoperative agitated delirium. Propensity score matching was conducted to balance various covariates known to influence dementia risk...

General anaesthesia is typically recommended for category 1 emergency caesarean delivery (CD). For categories 2-4 emergencies, either regional and general anaesthesia could be used. However, the factors influencing the choice of anaesthetic technique in these categories remain poorly understood. We analysed the association between the type of labour analgesia and subsequent anaesthetic techniques employed for intrapartum categories 2 and 3 CD. A prospective longitudinal cohort study was conducted at the University Medical Centre Ljubljana...

BACKGROUND: Spinal anaesthesia is widely used in obstetric anaesthesia practice but there is limited knowledge about the development of sympathetic blockade following spinal anaesthesia for caesarean birth. This study investigated the characteristics of sympathetic blockade by measuring peripheral skin temperature changes in the feet of patients given spinal anaesthesia for elective caesarean birth. METHODS: A prospective observational study was conducted involving 60 eligible parturients scheduled for elective caesarean birth with spinal anaesthesia...

BACKGROUND AND AIMS: Motor-sparing analgesia after total knee arthroplasty (TKA) is crucial. The primary endpoint was the postoperative visual analogue scale (VAS) score after triple injection peri-sartorius (TIPS) block after TKA. Secondary endpoints were postoperative morphine consumption, 24-h postoperative ambulation distances and the degrees of active knee extension. METHODS: After general anaesthesia or spinal anaesthesia administration and before surgical incision, 80 patients undergoing TKA were randomised into group TIPS (received ultrasound-guided TIPS block where 40 ml 0...

BACKGROUND AND AIMS: Thoracic continuous spinal anaesthesia (TCSA) is emerging as the sole anaesthetic for major abdominal surgery due to its better perioperative outcomes. This study was designed to evaluate block characteristics and outcomes in 'opioid-free' and 'opioid-based' TCSA. METHODS: After ethical approval, trial registration and written informed consent, 50 adult patients undergoing major abdominal surgery were randomised into 'opioid-free' (bupivacaine alone) and 'opioid-based' (bupivacaine with fentanyl) groups...

Introduction Transurethral resection of the prostate (TURP) is the standard surgical procedure for obstructive symptoms of the lower urinary tract when medical management fails. Progression in TURP procedures has led to reduced catheterization time following transurethral prostatic resection. This study describes the methods and results of TURP performed in the day surgery setting. Materials and methods This retrospective study was performed at a day surgical hospital serving a patient population of more than 200,000 people...

STUDY DESIGN: Narrative review. OBJECTIVE: The spine is the most common site of metastases, associated with decreased quality of life. Increase in metastatic spine tumour surgery (MSTS) has caused us to focus on the management of blood, as blood loss is a significant morbidity in these patients. However, blood transfusion is also not without its own risks, and hence this led to blood conservation strategies and implementation of a concept of patient blood management (PBM) in clinical practise focusing on these patients...

INTRODUCTION: In Anesthesia, a medication error would occur every 20 to 133 anesthesia procedures, and 14% is related to a route administration error. To secure neuraxial route, ISO group published a norm in 2016 to develop specific connectors, the "NRFit® connector". The main objective of this work, is to develop a risk mapping related to neuraxial medication errors therefore prepare the NRFit® implementation in Anesthesia units in a French universitary hospital. METHODS: FMECA (Failure Modes, Effects and Criticality Analysis) methodology was used for our risk mapping which was divided in 3 anesthesia specialities...
