Evaluation of Hemodynamic Changes and Fluid Response during Anesthesia in Lumbar Disc Hernias with Pleth Variability Index (PVI).

The study aimed to assess the pleth variability index (PVI) in patients undergoing lumbar disc herniation surgery under general and spinal anesthesia, exploring its correlation with fluid responsiveness, position, and hemodynamic parameters. Methods: This prospective study included 88 ASA 1-2 patients, aged 18-65, undergoing 1-3 h elective lumbar disc herniation surgery. Patients in groups GA and SA were observed for demographic, operative, and hemodynamic parameters at specified time points.

The Impact of CoronaVac Vaccination on 28-day Mortality Rate of Critically Ill Patients with COVID-19 in Türkiye.

Background: Vaccines against coronavirus disease-19 (COVID-19) have been effective in preventing symptomatic diseases, hospitalizations, and intensive care unit (ICU) admissions. However, data regarding the effectiveness of COVID-19 vaccines in reducing mortality among critically ill patients with COVID-19 remains unclear.

Aims: To determine the vaccination status and investigate the impact of the COVID-19 vaccine on the 28-day mortality in critically ill patients with COVID-19.

Comparison of the Efficacy of Two Different Plane Blocks in Isolated Bypass Surgery: A Prospective Observational Study.

Objective: This study evaluated the effects of serratus anterior plane block (SPB) and its combination with transverse thoracic muscle plane block (TTPB) on analgesia, opioid consumption, incentive spirometry performance, and patient comfort.

Design: A prospective, observational study.

Setting: A university hospital.

Dynamic thiol/disulphide balance in patients undergoing hypotensive anesthesia in elective septoplasties.

Objective: We aimed to investigate the effects of hypotensive anaesthesia on oxidative stress with serum thiol/disulphide balance in patients undergoing elective septoplasty procedures under general anaesthesia.

Methods: Seventy-two patients between the ages of 18-60, with a physical condition I -II, according to the American Society of Anesthesiologists, were included in this prospective observational study. Septoplasty was chosen for standard surgical stress.

COVID-19 infection produces subarachnoid hemorrhage; acting now to understand its cause: A short communication.

In the medical literature, some case reports on the association of the COVID-19 infection and occurrence of spontaneous subarachnoid hemorrhage (SAH)have been reported Aim of the present paper is to search the causes of this association The diagnosis of COVID-19 was based on the real-time reverse-transcription polymerase chain reaction (PCR) test and computed tomography (CT) of the chest. There were four patients, whose median ages were 46,758, ranged 36-54 years). In conclusion, Spontaneous SAH can occur in the early and late course of COVID-19 infection.

Comparison of the Effects of Minimal and High-Flow Anaesthesia on Cerebral Perfusion During Septorhinoplasty.

Objective: The aim of this study was to analyse the effects of minimal-and high-flow anaesthesia on cerebral oxygenation during septorhinoplasty with controlled hypotension using near-infrared spectroscopy.

Methods: Eighty patients scheduled for septorhinoplasty under general anaesthesia with controlled hypotension were randomised into two groups: minimal-flow (MF) or high-flow (HF). Both groups received desflurane anaesthesia to maintain bispectral index values at 40%-50% and 0.

Central Sagittal Angle of the Sacrum as a New Risk Factor for Patients with Persistent Low Back Pain after Caesarean Section.

Study Design: Retrospective.

Purpose: This study investigated the possible association of persistent low back pain (LBP) with caesarean section (CS) under spinal anesthesia.

Overview Of Literature: Many women suffer from LBP after CS, which is commonly performed under spinal anesthesia.

Complication of Peribulbar Block: Brainstem Anaesthesia.

Peribulbar block is used to obtain anaesthesia and akinesia of the eye by injecting a local anaesthetic around the musclecone. A patient scheduled for cataract surgery received peribulbar block with 6 mL of 2% lidocaine hydrochloride. Following the injection, confusion, hypotension and dilatation of the contralateral pupil rapidly progressed to loss of consciousness and respiratory arrest.
