... When the patient is in the Trendelenburg position again, the patient will experience an imbalanced ventilation/blood flow ratio, decreased lung ventilation, and decreased tidal volume, which may easily lead to hypercapnia. [15] In addition, the Trendelenburg position can prevent reflux from entering the airway by mistake and avoid suffocation. In our study, hypercapnia was not significantly different between the two groups. ...

... An SLT can be inserted via the intubating laryngeal mask airway, and then a BB can be used to achieve one-lung ventilation. Alternatively, a BB can be directly inserted via the laryngeal mask airway (119,120). For patients with tracheostomy, shortened DLTs or BBs can be considered to achieve lung isolation (2,121). ...

... As a result, our findings may be useful in anesthesiologists' , emergency physicians' , and paramedics' training and education. Finally, we performed a CUSUM analysis using the same parameters as the previous reports 10,13,14 . This allowed us to compare and interpret the characteristics of i-gel insertion with the other airway procedures during the early stages of learning. ...

... In addition, intranasal administration of dexmedetomidine has been investigated in studies involving children, which demonstrated that intranasal administration may be a feasible alternative in patients requiring light sedation (21,22); however, more attention should be paid to the differences in dexmedetomidine dosage between children and adults (15)(16)(17)(20)(21)(22). A number of studies have reported the application of intravenous dexmedetomidine in breast lumpectomy (23)(24)(25). Based on the similar efficacy between intravenous and intranasal administration, the present study hypothesized that intranasal dexmedetomidine may be effective in breast lumpectomy procedures. ...

... The use of gel or oily lubricant to coat the catheter surface and the application of laryngeal spray for surface anesthesia should be avoided. The depth (21-22 cm for men and 20-21 cm for women) and angle of the catheter should be properly adjusted (25). Good contact between the surface electrodes and the vocal cords should be ensured. ...

... Nair et al. demonstrated high placental retention related to the fat-soluble properties of dexmedetomidine [38]. Another study looked at the concentration of dexmedetomidine in breast milk and demonstrated minimal passage into the colostrum with a milk to plasma (M/P) ratio (at the highest doses studied) of 0.76 [36]. These authors concluded that because of dexmedetomidine's high degree of protein binding and higher molecular weight, it does not pass through the mammary epithelium easily. ...

... In the third category, the engineering is performed on the interaction parameters between the wave source and the object, i.e., the relative position of the needle to the ultrasound beam, including the incident angle of the ultrasound beam and the depth of insertion. An example of this interaction category is the utilization of a needle-guide kit to stabilize the needle (Ueshima and Kitamura 2015;Yoshmimura et al. 2016), and the technique of needle insertion, including in-plane and out-of-plane insertion technique (Maddali et al. 2017). ...

... Dexmedetomi-dine, which provides light sedation, possesses analgesic, sympatholytic, anxiolytic properties and attenuates the stress response without significant respiratory depression [7,8]. Due to the short half-life, dexmedetomidine was undetectable in milk at 24 hours after discontinuation of the administration and conducive to the early conversion of infant feeding to exclusive breastfeeding [9], suggesting that dexmedetomidine is compatible with breastfeeding [10]. Theoretically, dexmedetomidine might make it an ideal sedative for parturient with severe preeclampsia postoperative. ...

... Airway manipulation should be minimized to avoid sympathetic surge. Nakanishi et al. used Laryngeal mask airway ProSeal successfully in a MMD patient who underwent laparoscopic cholecystectomy [74]. The author proposes the use of LMA ProSeal as an effective alternative with minimal hemodynamic change, compared with tracheal intubation [75]. ...

... There is no consensus on the interpretation of P-wave morphology and its anatomical correlate, and this technique cannot be used in the absence of P waves (e.g., in cases of atrial fibrillation or cardiac pacing) [30][31][32][33][34][35][36]. The most accurate method for confirming CVC position is transoesophageal echocardiography (TEE) [37,38]. However, its invasiveness makes it unsuitable for everyday use. ...
