The optimum sevoflurane concentration for supraglottic airway device Blockbuster™ insertion with spontaneous breathing in obese patients: A prospective observational study

tailieu.vn

Conclusion: We conclude that the optimum end-tidal sevoflurane concentration required for the supraglottic airway device Blockbuster ™ insertion allowing spontaneous breathing in 50% of obese patients (ED 50 ) is . Keywords: Obesity, Spontaneous breathing, Sevoflurane, Supraglottic airway device. However, awake intubation may be difficult to perform in obese patients and cause distress to the patients [5].

Respiratory muscle activity after spontaneous, neostigmine- or sugammadex-enhanced recovery of neuromuscular blockade: A double blind prospective randomized controlled trial

tailieu.vn

These were recorded at the moment of resumed spontaneous breathing activity, defined as a maximal interval of 10 min after the first spontaneous breath.. Data were sampled from the start of spontaneous breathing, defined as EMG activity or clinical chest wall or abdominal wall motion or flow detected on the anesthesia ventilator, until extubation. We computed the median amplitude of EMG excur- sion from expiration to inspiration for the diaphragm and the intercostal muscles.

Volatile anesthetics maintain tidal volume and minute ventilation to a greater degree than propofol under spontaneous respiration

tailieu.vn

In the present study, both sevoflurane and isoflurane preserved spontaneous breathing and the ventilatory response to hypercapnia at sub-anesthetic concentra- tions. Although multiple sites contribute to the depressive effect of general anesthetics on respiration, the relatively selective maintenance of spontaneous breathing is poorly known. The mammalian pre-Bötzinger complex is an excitatory network of neurons in the medulla that is critically involved in respiration [27].

Another technique for weaning mechanical ventilation is the “ once - daily trial of spontaneous breathing ” (SBT). There were no signifi cant differences in the rate of success between a once - daily trial and the multiple daily trials (T - tube trial) of spontaneous breathing, or between intermittent mandatory ventilation and pressure support ventilation..

Role of inferior vena cava collapsibility index in the prediction of hypotension associated with general anesthesia: An observational study

tailieu.vn

The IVCCI was measured under spontaneous breathing. The performance of the IVCCI as a diagnostic tool for predicting hypotension (systolic pressure <. Results: A total of 83 patients were available for analysis, with 20 in the CI+ and 63 in the CI- group, we excluded 19 previously eligible patients due to inadequate visualization of the IVC (7 cases), lack of adherence to the protocol (8 cases), missing data (2 cases) or change in anesthesiologic management (2 cases).

Application of bedside ultrasound in predicting the outcome of weaning from mechanical ventilation in elderly patients

Anaesthesia and orphan disease: Management of a case of NicolaidesBaraitser syndrome undergoing cleft palate surgery

tailieu.vn

Overall, we recommend to perform a trial video assisted laryngoscopy in the setting of spontaneous breathing with deep inhalative. Nicolaides-Baraitser syndrome (NCBRS) is caused by mutations in the SMRCA2 gene, which affects chromatin remodelling and leads to a wide range of symptoms in- cluding sparse scalp hair, microcephaly, distinct facial features, short stature, recurrent seizures, and severe mental retardation [1–6]. The patient weighed 8 kg and was 77 cm tall.

Effects of dexmedetomidine on intraoperative hemodynamics, recovery profile and postoperative pain in patients undergoing laparoscopic cholecystectomy: A randomized controlled trial

tailieu.vn

This study showed that the spontaneous respiratory recovery time and extubation time increased more sig- nificantly in the experimental groups compared with NS group. The dexmedetomidine 0.8μg/kg group had the greatest effect on the spontaneous breathing time and extubation time, which was similar to previous studies . This may be related to “co-sedation” rather than over sed- ation of dexmedetomidine [8].

Feasibility of laryngeal mask anesthesia combined with nerve block in adult patients undergoing internal fixation of rib fractures: A prospective observational study

tailieu.vn

The patients’ Vt and RR during spontaneous breathing can meet the needs of intraoperative oxygenation, even in LMA anesthesia with 50% oxygen. Koo et al. Preoperative chest computed tomography showed a large amount of pleural effusion, incomplete atelec- tasis, and consolidation of the inferior lobe on the in- jured thorax.

Validity of mini-fluid challenge for predicting fluid responsiveness following liver transplantation

tailieu.vn

However, during the postopera- tive period, these methods are not feasible in patients with spontaneous breathing activity. In these cases, mini-fluid challenge has emerged as an alternative for preload challenge [3].. Several studies have investigated the value of mini-fluid challenge as a predictor of subsequent fluid infusion under different clinical conditions [4, 5]. However, none of these studies included patients with end-stage liver disease ESLD.

Positive - pressure ventilation, like the fi rst spontaneous breaths in the healthy infant, must establish FRC and an adequate tidal volume to halt the development or progression of the asphyxial process. To prevent overdistention of the lungs, the goal is to use just enough pressure to effect an improvement in heart rate, oxygen saturation/color, muscle tone and spontaneous breathing..

Procedural times in early non-intubated VATS program - a propensity score analysis

tailieu.vn

Surgery during spontaneous breathing can be challen- ging, not only because of a non-collapsing lung but as well from strong excursions of the diaphragm. The following limitations must be stated concerning our trial: First, as we conducted a single-center retro- spective study results may be difficult to transfer to other settings and resulted in inconsistent base line pa- rameters, e.g., the use of different opioids. Changes in staff might have had a considerable impact on procedural times.

Giáo trình Auto-PEEP

tailieu.vn

External PEEP, applied at the airway opening, will not worsen auto- PEEP if it does not exceed the critical pressure.. applying external PEEP (during mechanical ventilation) or continuous positive airway pres- sure (during spontaneous breathing) may reduce the work of breathing.. In other words, external PEEP should not be applied to all patients with airflow obstruc- tion who are mechanically ventilated—only those with auto-PEEP with flow limitation and dynamic airway compression..

Effect of topical ropivacaine on the response to endotracheal tube during emergence from general anesthesia: A prospective randomized double-blind controlled study

tailieu.vn

Machine-controlled breathing was shifted to manual breathing with ETCO 2 not exceeding 60 mmHg until the patients resumed spontaneous breathing. When the re- spiratory rate was greater than 10 breaths/min and tidal volume was more than 200 mL, the patients were trans- ferred to the post-anesthesia care unit (PACU) for wakeful- ness observation and extubation. The endotracheal tube was pulled out when the following parameters were met:.

Carbon dioxide pneumothorax following retroperitoneal laparoscopic partial nephrectomy: A case report and literature review
