Filter by:Spinal anesthesia is one of the commonest choices of anesthesia for infraumbilical surgeries.The use of sedation has markedly increased patients' comfort and acceptance towards spinal anesthesia. The aim of this study is to investigate visual, recall, auditory recall, and sedation scores among patients receiving Midazolam for sedation during spinal anesthesia in patients undergoing orthopedic surgeries.
Fluid therapy guided by stroke volume response to repeated fluid challenges is used for hemodynamic optimization during general anesthesia. Two types of devices that measure stroke volume non-invasively are primarily available for intermediate-risk surgery under general anesthesia. They are based on two different techniques, (1) pulse contour analysis, and (2) transthoracic bioimpedance. They have never been compared with each other. Therefore, it is not known (1) whether they are interchangeable for the measurement of stroke volume changes (usually assessed as the "concordance" of two techniques), and (2) whether one is better than the other. The aim is to study the concordance of these two non-invasive hemodynamic devices. it will use both of them in patients undergoing intermediate risk surgery. They will be tested during modifications of cardiac preload induced by Trendelenburg and anti-Trendelenburg positioning, as well as during intraoperative fluid challenges, vasopressor boluses and alveolar recruitment maneuvers.
Randomized single blind controlled clinical trial to test the benefit of sufentanil infusion over bolus dosing to reduce time to extubation and reduced length of ICU stay.
Anorectal surgeries are of the commonest elective surgeries that are performed worldwide under different types of anaesthesia. The aim of this prospective interventional study was to compare the use of general anaesthesia (GA) using a laryngeal mask airway (LMA) with spinal anesthesia (SA) in anorectal surgeries.
Recruitment maneuver is frequently used in daily anaesthesia routine to prevent athelectasia and ventilation perfusion mismatch. Especially pneumoperitoneum in laparoscopic surgeries affects the functional residual capacity (FRC) negatively. Recently, FRC can be measured at bedside in intensive care units. The lack of studies evaluating FRC measurements peroperatively and how recruitment maneuvers affect it, attract attention.
Infraclavicular nerve catheter for postoperative analgesia will be included in the 70 adult patients undergoing upper extremity surgery included in the study. These patients will be randomized to the catheter tip configuration as CEMP (closed-ended multiport catheter) group and OESP (open-ended single port catheter) group. Patient controlled analgesia device will be attached to the peripheral nerve catheter of these patients. Demographic data of the number of pushing the button, the amount of bolus dose given, the total dose given in the patient controlled anesthesia device, the need for additional analgesia and the amount, pain scores, complications will be recorded for three days postoperatively. Records will be compared statistically.
Noise in the operating room is common and often unavoidable, but there is mixed evidence of its impact. Previous research has suggested that excessive noise at the time when a patient is being 'put to sleep' may lead to care teams missing changes in monitors, having difficulties focusing or increasing stress. However, it is unknown ifs noise at this time affects the patient's satisfaction with the overall surgical experience. The investigators are conducting a survey study to evaluate patients' and anesthesiologists' overall satisfaction at the time of induction, before and after an education program promoting reducing noise in the Operating Room. Study Purpose: The purpose of this study is to investigate how noise levels that the time of induction in the OR (operating room) effect patient and anesthesiologists' satisfaction with the overall surgical experience. Hypothesis: The null hypothesis is that there is no improvement in patient satisfaction with the reduction of noise at the time of induction. Study Population: The Investigators will be including two study populations: patients age 19 or older undergoing elective, non-cardiac surgery with general anesthesia as the primary mode of anesthesia, and; Anesthesiologists working in these rooms. Research Method: This will be a pre/post survey study of patients and Anesthesiologists perspectives of noise in the OR. The investigators will survey participants before and after an educational intervention for OR staff.
Femoral nerve catheter for postoperative analgesia will be included in the adult patients undergoing total knee arthroplasty included in the study. These patients will be randomized to the catheter tip configuration as CEMP (closed-ended multiport catheter) group and OESP (open-ended single port catheter) group. Patient controlled analgesia device will be attached to the peripheral nerve catheter of these patients. Demographic data of the patients , the number of pushing the button the amount of bolus dose given, and the total dose given in the patient controlled anesthesia device, the need for additional analgesia and the amount, pain scores, complications will be recorded for three days postoperatively. Records will be compared statistically.
This study will compare an opioid free anesthetic, using dexmedetomidine, to a traditional opioid based anesthetic, using fentanyl, for patients undergoing cardiac surgery with regards to hemodynamic stability in the first 10 minutes after induction.
Acute appendicitis which is the most common cause of acute abdominal pain, is an acute inflammation of appendix vermiformis. Appendectomy operations can be performed as laparoscopic and open surgery. Addition of opioids to intrathecal local anesthetics to improve the quality of preoperative analgesia is an increasingly used method in recent years. The aim of this study is to compare bupivacaine-fentanyl and bupivacaine-alfentanil which are used intrathecally to create motor and sensory block. 50 volunteer patients who were diagnosed as appendicitis by laboratory tests and clinical diagnostic methods in general surgery clinic and classified as American Society of Anesthesiologists Classification I-II (ASA Class I-II) aged between 20-60 years scheduled for laparoscopic appendectomy operation, were included in this study. The patients were randomly assigned into two groups, Group I and Group II. Patients received spinal anesthesia with either 10 mg heavy bupivacaine (2 cc)+25 mcg fentanyl (0.5 cc) intrathecally (Group I, n=25) or 10 mg heavy bupivacaine (2 cc)+250 mcg alfentanil (0.5 cc) intrathecally (Group II, n=25).
