Filter by:This study aims to compare two groups of post-orthopedic patients who received a standard regimen, namely ketorolac 30mg, to the second group, which was given the standard regimen and adjuvant magnesium sulfate 30mg/kgBW 1 hour preoperatively. If it is proven useful, it is hoped that pain will be more controlled, reduce pain complications, reduce treatment costs, and reduce the duration of hospital stays.
With the introduction of technology into our lives, we come across two different anesthesia management modules in anesthesia machines. The first of these is the traditional method, the manual controlled anesthesia technique; the other is the automatic controlled anesthesia technique. In our daily practice, both anesthesia techniques can be used in patients who have undergone general anesthesia. These two techniques can be used in both high-flow anesthesia and low-flow anesthesia applications.
The purpose of the study is to compare Sphenopalatine ganglion block (SPGB) and aminophylline in the efficacy and safety management of PDPH.
High-flow nasal cannula (HFNC) oxygen therapy represents an open circuit ventilation system that uses flows up to 70 L/min of 100% oxygen through the Optiflow THRIVETM device (Fisher and Paykel Healthcare Ltd, Auckland, New Zealand). Compared to conventional oxygen therapy systems, the heating and humidification of the flows facilitate tolerability by the patient, allow to reach higher and more stable inspiratory fractions of oxygen, produce a flow-dependent effect of continuous positive airway pressure and by reducing dead space, have the potential to increase alveolar volume and improve gas exchanges. The use of HFNC is increased in anesthesia as the only airways management technique during short-term procedures under procedural sedation or general anesthesia. Operative hysteroscopy is a short-term procedure (<30 minutes), usually performed in a day-hospital regimen, under procedural sedation. In case of apnea and/or hypoventilation, or for long and complex hysteroscopic procedures, the patient can be ventilated through facial or laryngeal masks. The primary objective of this prospective randomized controlled trial is to compare the rate of success of ventilation using the THRIVE device to laryngeal mask ventilation during operative hysteroscopies under procedural sedation. Secondary objectives will be the comparison of the percentage of complications in terms of inability to manage the airways, episodes of hypotension, cardiac arrhythmias, post-operative nausea and vomiting, degree of dyspnea and comfort of the patient in the Post-Anesthesia Care Unit between the two methods.
Intrathecal morphine and fentanyl are used for anesthesia and perioperative pain management in caesarian section. Despite the fact that spinal Fentanyl is better tolerated, might not be enough for postoperative pain control. Morphine offers an improved analgesia but might be not tolerated due to a higher incidence of side effects, especially nausea and vomiting. This is a prospective, randomized, double-blind, parallel study including 80 parturients scheduled for elective CS. Spinal anesthesia is consisting in bupivacaine (7.5 - 10 mg in relation to height) and either fentanyl 25 mcg (F group) either morphine 100 mcg (m group). It will be assessed intraoperative and postoperative pain scores, the incidence of sides effects, patient's satisfaction and systemic opioids consumption.
The aim of this study is to evaluate the feasibility of the Pectoralis Nerve (PECS) block for CIED insertion.
The investigators aim to determine if the modification of the end inspiratory pause (EIP) during mechanical ventilation adds benefit when applied to patients undergoing robotic surgery and who are ventilated under an individualized open lung approach (iOLA) strategy. The EIP is an adjustable parameter of volume controlled ventilation modes usually set as a percentage of the total inspiratory time. It represents the phase comprised between the moment in which the volume programmed in the ventilator has already been administered (which marks the end of the inspiratory flow), and the opening of the expiratory valve (which marks the beginning of expiration). The investigators will study whether modifications of the EIP produce variations in the "quantity" of the lung that participates in gas exchange (respiratory volume). To do so, the investigators will sequentially apply different EIP to participants (paired study). The investigators´ hypothesis is that increasing the EIP up to a level, may diminish the lung volume that does not participate in breathing (the physiological dead space- VDphys), thereby increasing the respiratory volume. To note: the VDphys includes the "conduction" volume, that represented by trachea, bronchi, et cetera, which is in charge of driving the "air" towards the respiratory zones, and the alveolar dead space (those zones of the respiratory volume that due to different reasons do not directly participate in gas exchange: alveoli ventilated but not perfused, areas of overdistension, etc. The investigators will measure dead volumes by mean of specific non-invasive monitoring (volumetric capnography) coupled to the anesthesia workstation, and the mechanics of lung and the distribution of the gas within it by means of electric impedance tomography, a non-invasive technique showing continuous images of patient's lung. The estimation of the respiratory volume will help the investigators to more precisely adjust the amount of oxygen and anesthetic gases that must be administered in function of patients´ gases consumption, a calculated parameter that is function of the respiratory volume and that will also be tested during the study. The investigators will also accurately measure patient oxygenation by means of arterial blood samples extracted from a radial artery catheter. Apart from sequential modifications in the EIP, the ventilation strategy applied to patients will be that used in the investigators´ usual practice (described below).
Dacryocystorhinostomy aims to create a channel between the lacrimal sac and nasal mucosa to relieve nasolacrimal duct occlusion. General anesthesia is still preferred by many surgeons to secure the airway and control blood pressure.
Patients undergoing surgery inside their abdomen, with no serious heart or lung diseases, will have a lung ultrasound exam before and after surgery. The patient respiratory status in the post-operative unit and the surgical ward will be monitored for complications after surgery
The purpose of this study is to characterize the effects of intravenous lidocaine on pain processing and cognitive function. Functional magnetic resonance imaging will be used to identify the neural correlates of these phenomena. The study will consist of 1 visit and involves no long-term follow up.
