The Evolving Role of Chlorthalidone and Hydrochlorothiazide as First-Line Treatments for Hypertensive Patients.

Hypertension is attributable long-term to various negative health outcomes, including atherosclerotic cardiovascular disease and, more broadly, to cardiovascular events such as congestive heart disease, myocardial infarction, heart failure, and stroke. Effective hypertension treatment is essential to lower the risk of these outcomes. Treatment of hypertension includes both nonpharmacologic and, if necessary, pharmacologic interventions. The drug classes proven in trials to decrease the risk of cardiovascular disease events in cases with hypertension include angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, thiazide diuretics, and calcium channel blockers. When considering thiazide diuretics as a first-line treatment, chlorthalidone (CTD) is currently recommended by the American College of Cardiology over hydrochlorothiazide (HCTZ). Previous studies have demonstrated that CTD is superior to HCTZ in preventing cardiovascular disease events. However, more recent studies have revealed that there is no significant difference in the results of patients treated with HCTZ versus those treated with CTD. Additionally, studies have revealed CTD has worse outcomes regarding side effects when compared to HCTZ. In this regard, it is essential to carefully consider which medication will best improve the outcomes of patients with hypertension while also causing few or easily manageable side effects.

Safety, Efficacy, and Ease of Insertion of Gnana Laryngeal Airway (GLA-4): A Prospective Clinical Study Utilizing the Unique Laryngeal Mask Airway With a Suction Tubing.

INTRODUCTION: Utilizing laryngeal mask airways to maintain patients' airways is advantageous because it enables the anesthesiologist to keep the patient spontaneously inhaling and is less traumatic to the airway than intubation. Newer designs such as the Gnana laryngeal mask airway design permit real-time suctioning while the mask is on a patient. METHODS: This is a prospective observational study of the efficacy of Gnana laryngeal airway 4 (GLA-4) in 50 patients undergoing colonoscopy. Induction and maintenance of anesthesia were provided with propofol; GLA-4 was applied to secure the airway; and correct placement was verified. RESULTS: Fifty patients were included in the study (44% female, 56% male, mean age: 56.5 years, mean BMI: 33.3). Twelve patients were assigned American Society of Anesthesiologists (ASA) class 2, and 38 were assigned ASA class 3. The first attempt of GLA-4 insertion was successful in 47 patients, and two attempts were required for the successful placement of the GLA-4 in two patients. The successful placement was not achieved in one patient. The average time to successful insertion was 27.1 ± 3.9s. The average volume of oropharyngeal secretions suctioned through the suction catheter was 9.96 ± 2.31 mL. No intraoperative or postoperative complications occurred in the 50 patients. There were no reports of sore throat, hoarseness, dysphagia, or cough immediately postop. CONCLUSION: GLA-4 can be inserted safely with adequate periglottic occlusion. This laryngeal mask is unique and desirable due to its ability to evacuate oropharyngeal secretions while in place to prevent laryngospasm. To establish the role of GLA-4 in broader clinical situations, additional clinical trials and studies are required.
