Correlation of important prognostic factors and CT scores in invasive and non-invasive ventilation of COVID-19 patients.

Background: Intensive care workers received the largest share of the COVID-19 pandemic, which caused nightmares to the whole world. In COVID-19 pneumonia cases which had high mortality rates, many prognostic factors and laboratory examinations were tried to evaluate the clinical severity quickly and accurately.This study was planned to investigate a correlation between the initially ventilation strategy and major prognostic parameters and CT scores in patients admitted to intensive care unit (ICU).

Factors affecting mortality in COVID-19 patients in intensive care.

Background: The COVID-19 pandemic affects the whole world, causing high mortality. Some clinical parameters have already been implemented to be followed up to prevent mortality, but there is still a need for further information about optimum follow-up parameters and cutoff values. We aimed to investigate the reliability of the parameters used in patient follow-up by comparing survivors and non-survivors.

[Effects of local anesthetics on wound healing].

Introduction: Local anesthetic infiltration is used widely for post-operative analgesia in many situations. However the effects of local anesthetics on wound healing are not demonstrated clearly. This study planned to evaluate the effects of lidocaine, prilocaine, bupivacaine and levobupivacaine on wound healing, primarily on wound tensile strength and on collagen ultrastructure.

Our intraoperative boost radiotherapy experience and applications.

Objective: To present our experience since November 2013, and case selection criteria for intraoperative boost radiotherapy (IObRT) that significantly reduces the local recurrence rate after breast conserving surgery in patients with breast cancer.

Material And Methods: Patients who were suitable for IObRT were identified within the group of patients who were selected for breast conserving surgery at our breast council. A MOBETRON (mobile linear accelerator for IObRT) was used for IObRt during surgery.

Effects of positive end-expiratory pressure on arthroscopic shoulder surgery under general anesthesia.

Objective: Our study is a prospective, randomized study on patients undergoing arthroscopic shoulder surgery in the beach-chair position to evaluate the effects of positive end-expiratory pressure (PEEP) on hemodynamic stability, providing a bloodless surgical field and surgical satisfaction.

Methods: Fifty patients were divided into two groups. Group I (n=25) had zero end-expiratory pressure (ZEEP) administered under general anesthesia, and group II (n=25) had +5 PEEP administered.

[The cognitive effects of using transdermal fentanyl in cancer pain].

Objectives: In this study, we aimed to investigate the effects of using transdermal fentanyl (TDF) on cognitive functions in cancer pain.

Methods: After approval and informed consent of patients by the Ethical Committee, fifty patients with cancer pain who had no previous opioid treatments were included in the study. Pain was evaluated with Visual Analogue Scale (VAS) while, cognitive functions were assessed using by Addenbrooke's Cognitive Examination final revised version (ACE-R).

Effects of glutamine on wound healing.

Studies reporting the need for replacing amino acids such as glutamine (Gln), hydroxymethyl butyrate (HMB) and arginine (Arg) to accelerate wound healing are available in the literature. The primary objective of this study was to present the effects of Gln on tissue hydroxyproline (OHP) levels in wound healing. This study was conducted on 30 female Sprague Dawley rats with a mean weight of 230 ± 20 g.

[The comparison of epidural continuous infusion and epidural patient controlled bolus administration in labor analgesia].

Objectives: We aimed to compare the efficacies of patient controlled bolus administration and continuous infusion of low dose Fentanyl and Levobupivacaine combination by epidural catheter during vaginal labor on mother, baby and the duration of labor.

Methods: The 45 pregnant women involved in the study were divided randomly into two groups, Group HKEB (patient controlled epidural bolus) and Group SEI (continuous epidural infusion). Hemodynamic parameters and VAS values of the pregnant women, fetal heart rate, Apgar scores, duration of labor stages, types of delivery and side effects were recorded.

Comparison of the anesthetic effects of intrathecal levobupivacaine + fentanyl and bupivacaine + fentanyl during caesarean section.

Background: Regional anesthesia techniques are increasingly preferred for caesarean section. The aim of the present study was to compare the anesthetic effects of levobupivacaine + fentanyl and bupivacaine + fentanyl on the mother and newborn during elective caesarean section under spinal anesthesia.

Methods: In this prospective study, 50 gravidas, who were scheduled for cesarean section were enrolled after Ethics Committee approval had been obtained.

[Comparison of non-invasive mechanical ventilation with helmet or face mask in patients with acute exacerbation of chronic obstructive pulmonary disease].

Exacerbation of chronic obstructive pulmonary disease (COPD) is one of the frequent causes of acute respiratory failure. In our study, we aimed to compare helmet with face mask in noninvasive mechanical ventilation (NIMV) on patients who had acute respiratory failure because of exacerbation of COPD in intensive care unit (ICU). Thirty patients, taken into ICU for exacerbation of COPD, were included in the study.

Comparison of the laryngeal mask airway Supreme and laryngeal mask airway Classic in adults.

Background And Objective: The laryngeal mask airway (LMA) is an important airway device that was developed in 1983. From the first classic LMA models up to now, LMA models have been developed that are easily and quickly inserted, provide ventilation at higher airway pressures, have lower cuff pressure, a reduced risk of gastric aspiration and cause fewer stress responses. We aimed to compare the LMA Classic with the LMA Supreme in assessing the success rate and time for insertion, number of attempts and leak pressure.

Remifentanil-propofol vs dexmedetomidine-propofol--anesthesia for supratentorial craniotomy.

The aim of the present study was to compare the perioperative hemodynamics, propofol consumption and recovery profiles of remifentanil and dexmedetomidine when used with air-oxygen and propofol, in order to evaluate a postoperative analgesia strategy and explore undesirable side-effects (nausea, vomiting, shivering). In a prospective randomized double-blind study 50 ASAI-III patients scheduled for supratentorial craniotomy, were allocated into two equal Groups. Group D patients (n = 25), received i.

Comparison of percutaneous dilatational tracheostomy with surgical tracheostomy.

Rationale: Tracheostomy is done mostly in critically ill patients, many of whom may not survive. We still do not know the long term complications of tracheostomy itself; tracheal and subglottic stenosis, and tracheomalacia.

Objectives: To compare the complications of surgical tracheostomy (ST) versus percutaneous dilatational tracheostomy (PDT) by means of MRI control up to 1 month after closed tracheostomy.

Positive end-expiratory pressure reduces pneumocephalus in spinal intradural tumor surgery.

We tested the hypothesis that 5 cm H2O of positive end-expiratory pressure (PEEP) reduces the incidence of pneumocephalus in patients who undergo spinal intradural tumor surgery. Fifty-three ASA I to III patients who underwent thoracolumbar intradural tumor surgery between the years 2003 and 2006 were included in this study. All patients received propofol, fentanyl, and cisatracurium for induction of the anesthesia.
