Filter by:This study evaluates the analgesic effects of pectoralis nerve block (PECS II) and erector spinae plane block (ESP) in patients having segmental mastectomy and sentinel lymph node biopsy (SLNB). Each one-third of patients will have ESP block and pectoralis nerve block (PECS II) 30 min before general anesthesia , while other one-third of patients will have only general anesthesia.
MET-REPAIR CONVAL is an international cohort study to examine the ability of self-reported exercise capacity to predict perioperative cardiovascular events correcting for preoperative risk factors.
This study is designed as a single-center, prospective observational, non-controlled, non-interventional study with an investigation period lasting for one day (during one bronchoscopy procedure). The study will take place in Denmark. The study will include minimum 15 and maximum 20 adult patients planned for a diagnostic flexible bronchoscopy procedure in general anaesthesia using a laryngeal mask. The involved site will include subjects during a one month period, October 2019. The intention is to perform a quality assessment of the AuraOnce. Subjects will not be asked to participate in this study as it is a quality study where the AuraOnce is used within its intended use and according to normal clinical procedure.
There are different types of pain generators that give different pain symptoms. In anesthesia and surgery, the pain generator in connection with, for example, surgical procedures is referred to as nociceptive pain. However, there is not enough evidence to support that these physiological changes are direct signs of nociceptive stimulation. The same changes can be seen with an autonomous stress trigger of origin other than just nociceptive stimulation. This means that healthcare professionals who provide anesthesia to patients during, for example, surgery may provide unnecessary pain relief drugs or do not provide pain relief when needed. This is also true in awake patients when pain is complex that, for example, concerns may increase the experience of pain and that healthcare professionals may even then misinterpret and provide more pain-relieving drugs despite the actual need for another drug or complementary treatment. Examples of these include heart rate variation, specific patterns in blood pressure and heart rate response, heart rate amplitude, heart rate range, skin sweating and pupil response. The reason why these changes have not been used to interpret nociceptive stimulation is directly linked to an absence of technology that makes it possible to collect data and interpret these changes. list a number of methods / techniques that are under development, one of which is the Nociception Level Index (NoL). NoL is an indexed value between 0 and 100 and is based on a non-linear combination of nociception-related physiological variables (including heart rate variation, plethysmograph pulse wave amplitude (PPGA) and changes in skin resistance). Possibly NoL is the first evidence-based clinical technology that can discriminate pain response when physiological response is not measured. The research field in the area of non-invasive objective monitoring of pain response in relation to patients' experience of pain is currently almost non-existent in anesthesia / anesthesia care This in turn can also lead to the development of patient safety both during anesthesia and after surgery at nursing department for example, patient-controlled and epidural pain relief in postoperative pain care. investigators intend to study the variation of the NoL index linked to the need for opioids during anesthesia and also after completed anesthesia when the patient wakes up and is in the ward.
Opioid-free anesthesia (ATO) is a multimodal anaesthesia combining different analgesic and anesthetic modalities thus excluding opiates as an intraoperative. Recent studies have found a benefit from the ATO on postoperative rehabilitation and reduced length of hospitalization. Periarticular infiltration with a local anesthetic is one of the measures proposed in OFA during the PTH. PTH remains a painful procedure and the occurrence of morphinic-related side effects in sometimes elderly patients is often observed. The main objective of this study is to assess the feasibility of ATO in anterior hip replacement under general anesthesia with the primary endpoint of morphine consumption measured 24 hours after surgery.
To investigate if signal processing can detect subtle changes in speech production clinically relevant to oropharynx anatomy that may provide an objective measure in the assessment of the presumed difficulty of intubation.
Processed electroencephalogram (EEG) monitors are routinely used in addition to clinical parameters to assess the depth of anaesthesia during general anaesthesia.
Cerebral blood flow is tightly regulated to ensure constant cerebral perfusion independently from systemic blood pressure fluctuations. This mechanism is termed cerebrovascular autoregulation and preserves adequate cerebral perfusion in a range between 50 and 150 mmHg of cerebral perfusion pressure. Upper and lower autoregulatory limits may vary individually. Beyond the autoregulatory range the protective autoregulatory response is lost, facilitating cerebral ischemia or hyperemia. The cerebrovascular response may be altered during general anesthesia, through direct effects of anesthetic agents on the vascular tone, changes of arterial partial pressure of carbon dioxide or the administration of vasoactive substances. The association of perioperative impairment of cerebral autoregulation and postoperative cognitive function has been discussed controversially.
Currently there no standard sedation techniques for performing ERCP. It is not clear whether sedation administered by anesthetist is better than anesthesia with intratracheal intubation. To clarify which of these sedative methods are better we plan to conduct a randomized trial comparing anesthetist administered sedation with general anesthesia in patients with ASA ≤3.
to evaluate the difference between the tracheal intubation (TI) and rigid bronchoscopy (RB) under general anesthesia on patients with transbronchial cryobiopsy.
