Filter by:the investigators aim in this study is to determine whether the block is successful in successful infraclavicular brachial plexus blocks performed with USG, according to the change in GSR value in the upper extremity blocked due to sympathetic nerve blockade. Block success will be evaluated by sensory and motor examination of the blocked arm.
Funnel chest deformation is a painful procedure, which requires high doses and long time used of opioids. It makes difficult introduction of ERAS protocol. Intraoperative cryolesia of intercostal nerves serves great relief of pain after this procedures. However ablation of the nerves needs 12-24 hours to achieve effects. During this time the high doses of opioids are needed. It causes side effects (sedation makes rehabilitation difficult). On the other hand, percutaneus cryoablation performed 12-24 hours before Nuss procedure needs repeated general anaesthesia. The investigators hypothesed that regional analgesia (erector spine plain block) performed just before intraopertive cryolesia may cover time to full cryolesia effect.
Paravertebral block (PVB) has been regarded as effective regimen for pain control after cardiac surgery. As a novel analgesia technique, erector spinae plane block (ESPB) has been reported to provide effective analgesia after thoracic and cardiac surgery. We hypothesized that the ESPB is non-inferior to PVB in treating pain in minimally invasive direct coronary artery bypass surgery.
The aim of the trial is to study the efficacy of continuous bilateral Erector Spinae Plane Block (ESPB) in managing perioperative pain in patients who undergo elective laparoscopic colectomy.
Obesity is a health problem throughout the world and has increasingly become a widespread epidemic all over the world and also in Turkey. Anesthesia management of obese patients is challenging because of difficult airway, increased drug doses, co-morbidities, loss of anatomical landmarks and difficulties in positioning. Neuroaxial and peripheral nerve blocks are widely used in anesthesia practice in both obese and non-obese patients undergoing different surgical operations. In this prospective observational study, the investigators plan to enroll all patients that are applied neuroaxial or peripheral blocks during the study period. The aim of this study is to compare the differences and difficulties of regional anesthesia/analgesia techniques in obese and non-obese patients.
The objective of the study is to compare the efficacy of the Serratus Anterior Plane block (SPB) realised in its deep plane, with a multi-holed catheter in place for twenty four hours, to a standard intravenous analgesia for small videoassisted thoracic surgery interventions. The objective is also to evaluate the resorption rate of local anesthetic at this level, and make a population pharmacokinetic analysis.
The authors study the efficacy of the pudendal versus penile block for the relief of postoperative pain in children receiving ambulatory circumcision. In this prospective, double-blind, randomized, parallel-arm trial, 60 children recruited during the anesthesia consultation will be allocated a general anesthesia with a pudendal block (PUD group) or a penile block (PEN group). Each block will be made with equal parts lidocaine 1% and ropivacaine 0.75% (0.3 ml/kg).
In this study, we will be comparing two approaches to the femoral block. The first or classical approach and one that is the most popular in our institution is used by combining ultrasound guidance and neurostimulator to do the block. The second is performed with the ultrasound alone aiming at the inferolateral aspect of the femoral artery with the needle and injecting. The primary endpoint of the study is the sensitive cutaneous block distribution using both techniques.
Aim oft he study is to compare two different devices for cerebral oximetry (FORE-SIGHTTM Monitor (CAS Medical Systems, Branford, Connecticut, USA and INVOSTM Somanetics, Troy, Michigan, USA) in patients undergoing surgical carotid thrombendarterectomy (cTEA) with crossclamped internal carotid artery (ACI). All procedures will be performed in regional anesthesia, therefore the patients will be awake and direct neurological examination during the procedure will be possible, giving information how the drop in cerebral saturation (measured with INVOS and FORESIGHT both on the same patient) correlates with any clinical symptoms. We expect to see a difference in the total drop and in the delay of the drop of cerebral oxygen saturation, making it possible to detect varieties in specificity and sensitivity of both devices compared to neurologic examination in the awake patient.
