[Efficacy of stellate ganglion block in perioperative period of patients with chronic sinusitis and hypertension].

To observe the perioperative efficacy of stellate ganglion block (SGB) in functional endoscopic sinus surgery (FESS) in chronic sinusitis patients with hypertension. A total of 60 patients with chronic sinusitis complicated with hypertension who were scheduled to undergo FESS in the Department of Otorhinolaryngology, the First Affiliated Hospital of Soochow University from April 2018 to December 2019 were selected and divided into SGB group and control group by random number table method. SGB were performed at 24 hours before surgery and induction of general anesthesia alternately, while the control group was not treated. During the operation, controlled hypotension were performed in both groups. Hemodynamic parameters such as systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP) and heart rate (HR) were recorded at 24 hours before surgery(T(0)), before anesthesia induction (T(1)), at the beginning of surgery (T(2)), at the end of surgery (T(3)), and at 24 hours after surgery(T(4)).Plasma epinephrine and norepinephrine concentrations were measured at T(0), T(1), T(3) and T(4). The dosage of anesthesia and other drugs, operative time, bleeding amount and extubation time were recorded, while the quality of the operative field was evaluated. VAS scores were assessed at 1, 6 and 24 hours after surgery. In the SGB group, SBP, DBP and MAP in T(1), T(2), T(3), T(4) and HR in T(1), T(4) were lower than those in the control group (all 0.05). Compared with T(0), SBP, DBP, MAP and HR in T(1), T(2), T(3), T(4) all decreased in SGB group (all 0.05); In the control group, SBP, DBP and MAP only decreased in T(2) and T(3), and HR fluctuated significantly (0.05). In the SGB group, plasma epinephrine and norepinephrine concentrations at T(1), T(3) and T(4) were lower than those in the control group (0.05). Compared with T(0), plasma epinephrine and norepinephrine concentrations in the SGB group fluctuated in positive and negative phases, while those in the control group increased (0.05). The pain scores in SGB group at 6 and 24 hours after surgery were 1.3±0.7 and 2.6±0.9, which were lower than 1.7±0.7 and 3.1±0.9 in the control group (-2.290, -2.050, all 0.05). SGB may effectively improve hemodynamics, maintain homeostasis, reduce anesthesia and surgical complications in patients with chronic sinusitis and hypertension in perioperative period.
