Background: Esmolol has an established role in attenuation of hemodynamic response to laryngoscopy and endotracheal intubation. We studied the effect of dexmedetomidine compared to that of esmolol in this study.
Aim: To study the role of dexmedetomidine in attenuation of hemodynamic response to laryngoscopy and oral endotracheal intubation compared to that of esmolol hydrochloride in patients posted for elective surgery under general anesthesia.
Study Design: Prospective randomized study double-dummy blinding method.
Materials And Methods: A total of 60 American Society of Anesthesiologists I patients, aged 18-60 years randomly divided into two groups; Group A patients received dexmedetomidine 1 mcg/kg diluted in 50 ml with normal saline and infused over 10 min before induction and also 20 ml of normal saline intravenous (IV) 2 min before endotracheal intubation. Group B patients received 50 ml IV infusion of normal saline over 10 min before induction and IV bolus of esmolol 0.5 mg/kg diluted in 20 ml with normal saline given 2 min before intubation. Standard induction technique followed. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were recorded just before induction and after intubation at 1 min, 3 min, and 5 min after intubation.
Statistical Analysis: Independent samples t-test and repeated measures of analysis of variance.
Results: Dexmedetomidine group showed statistically significant reduction in all the study parameters at all study time intervals following intubation. While esmolol group showed significant attenuation of HR, SBP, and MAP following intubation but failed to produce significant reduction in DBP.
Conclusion: Dexmedetomidine is more effective in attenuating the hemodynamic response to oral endotracheal intubation compared to that of esmolol hydrochloride.

Ciprofol, a novel γ-aminobutyric acid receptor agonist, outperforms propofol with minimal cardiovascular effects, higher potency, reduced injection pain, and a broader safety margin. Despite these advantages, ciprofol's clinical research is still emerging. This study compares the median effective dose (ED) and adverse reactions of ciprofol and propofol, in conjunction with sufentanil, for suppressing cardiovascular responses during tracheal intubation.

Background: Airway management is a critical component of the care of patients experiencing cardiac arrest, but data from randomized trials on the use of video vs direct laryngoscopy for intubation in the setting of cardiac arrest are limited. Current AHA guidelines recommend placement of an endotracheal tube either during CPR or shortly after return of spontaneous circulation but do not provide guidance around intubation methods, including the choice of laryngoscope.
Research Question: Does use of video laryngoscopy improve the incidence of successful intubation on the first attempt, compared to use of direct laryngoscopy, among adults undergoing tracheal intubation after experiencing cardiac arrest?
Study Design And Methods: This secondary analysis of the Direct versus Video Laryngoscope (DEVICE) trial compared video laryngoscopy versus direct laryngoscopy in the subgroup of patients who were intubated following cardiac arrest.

Background: Proficiency in endotracheal intubation (ETI) is essential for medical professionals and its training should start at medical schools; however, large caseload may be required before achieving an acceptable success rate with direct laryngoscopy. Video laryngoscopy has proven to be an easier alternative for intubation with a faster learning curve, but its availability in medical training may be an issue due to its high market prices. We devised a low-cost 3-dimensionally printed video laryngoscope (3DVL) and performed a randomized trial to evaluate if the intubation success rate on the first attempt with this device is noninferior to a standard commercially available video laryngoscope (STVL).

Background: Several health care networks have fully adopted second-generation supraglottic airway (SGA) i-gel. Real-world evidence of enhanced patient safety after such practice change is lacking. We hypothesized that the implementation of i-gel compared to the previous LMA®-Unique™ would be associated with a lower risk of airway-related safety events.

Patients with selective IgA deficiency could have various clinical presentations ranging from asymptomatic to severe respiratory or gastrointestinal tract infection, as well as autoimmune disease and allergic reactions. Selective IgA deficiency is relatively common in Caucasians, but it is rare in the Asian population, meaning it could be easily missed in the clinic. In this study, we report a 26-year-old man with a history of asthma and nephrotic syndrome.
