More hypotension in patients taking antihypertensives preoperatively during shoulder surgery in the beach chair position

The Effect of Ultrasound-Guided Interscalen Brachial Plexus Block Plus General Anesthesia for Postoperative Pain in Arthroscopıc Shoulder Surgery

“…Ancak bu çalışmada her iki grupta da solunum sıkıntısı görülmedi. Çeşitli çalışmalarda interskalen blok ve GA gruplarında vazopresörlerle tedavi gerektiren hipotansiyon komplikasyonlarına rastlanmaktadır (31)(32)(33). Bu çalışmada ise İSBPB grubunda 33 (%58,9) hastada, GA grubunda ise 21 (%50) hastada hipotansiyon gözlenmişti, ancak aralarında anlamlı fark bulunmamıştı.…”

Randomized Trial of the Use of Dexmedetomidine vs. Propofol after Regional Blockade in Shoulder Surgery Patients in Beach Chair Position

“…In the past, some practitioners have deferred from utilizing dexmedetomidine given reports of profound bradycardia and hypotension [2], especially in the setting of hypovolemia, diabetes mellitus, chronic hypertension and antihypertensive therapy, heart block, ventricular dysfunction, in elderly, and in surgery in the head-up or sitting positions [3].…”

Blood pressure management during beach chair position shoulder surgery: What do we know?

“…At the present time, however, several important questions about ''best practices'' for blood pressure management in the BCP remain unanswered. In this issue of the Journal, the investigations by YaDeau et al 6 and Trentman et al 7 provide important data in this ongoing debate about the prevalence, risk factors, and potential consequences of hypotension during shoulder surgery in the sitting position.…”

“…In the investigation by Trentman et al, they examined the incidence of hypotension in patients undergoing general anesthesia during shoulder surgery in the BCP. 7 Although the use of antihypertensive agents has been shown to be associated with a greater incidence of hypotension in supine patients under general anesthesia, 12 this relationship has not been previously examined in sitting patients. Medical records were reviewed retrospectively to determine the incidence of hypotensive episodes (systolic blood pressure B 85 mmHg-not corrected to account for differences in height between site of measurement and the brain) in normotensive or treated hypertensive patients.…”

“…Dans l'étude de Trentman et coll., les auteurs ont examiné l'incidence de l'hypotension chez les patients subissant une anesthésie générale pendant une chirurgie de l'épaule en position assise. 7 Bien qu'il ait été démontré que l'utilisation d'agents antihypertenseurs était associée à une incidence plus élevée d'épisodes d'hypotension chez les patients en position couchée sous anesthésie générale, 12 cette relation n'a pas été examinée chez les patients en position assise. Les dossiers médicaux ont été rétrospectivement passés en revue afin de déterminer l'incidence d'épisodes d'hypotension (une tension artérielle systolique B 85 mmHg n'a pas été corrigée afin de tenir compte des différences de hauteur entre le site de mesure et le cerveau) chez des patients normotendus ou des patients hypertendus traités.…”
