RESUMEN
Objective To compare the difference in dose of general anesthesia between pastoral patients and urban pa-tients.Methods The patients who performed abdominal surgery under general anesthesia in Peoples hospital of Bortala Mongo-lian Autonomous Prefecture from January 1st to April 30th 2022 were included and divided into pastoral patient group and ur-ban patient group according to the residential place of patients.Anesthesia and surgery were carried out according to hospital regulations.The general characteristics of all patients were recorded and the dosages of general anesthesia drugs were compared between the two groups.Results There was no significant difference between the two groups in general and intraoperative con-ditions.Patients'performances were stable,and no severe adveres reaction was observed.The dosages of Propofol,Remifen and Rocuronium in pastoral patients were higher than that in urban patients(all P<0.05).Conclusion The dosage of general anes-thesia for patients in pastoral areas is higher,which ensures the stability of anesthesia depth and vital signs of patients,creates good conditions for surgery and promotes rapid recovery of patients.
RESUMEN
RESUMEN El edema pulmonar por presión negativa es una complicación rara y dramática en la anestesia general. Habitualmente ocurre como consecuencia de un laringoespasmo u otra causa de obstrucción de la vía aérea. Se presentó un caso con el objetivo de mostrar los elementos usados para el diagnóstico y tratamiento del edema pulmonar por presión negativa. Paciente de 7 años de edad, femenina, ASA I, operada de metatarso varo funcional con anestesia general balanceada y máscara laríngea clásica # 3. Desarrolló dicho evento adverso durante la recuperación anestésica. El diagnóstico se basó en la disociación toraco abdominal al restablecer la ventilación espontanea, crepitantes en ambos hemitórax, cianosis central, hipoxemia y la presencia de infiltrado difuso bilateral alveolar. Se intubó la tráquea, se controló la ventilación con presión positiva al final de la espiración y se administró furosemida. La paciente fue trasladada a la Unidad de Cuidados Intensivos donde evolucionó satisfactoriamente. Este es un síndrome cuya verdadera incidencia se desconoce debido a la escasa familiarización con el mismo. La evolución de los pacientes es favorable siempre que se establezca el diagnóstico y el tratamiento oportuno (AU).
ABSTRACT Pulmonary edema due to negative pressure is a rare and dramatic complication in general anesthetic. It usually occurs as a consequence of a laryngeal spasm or another cause of respiratory tract obstruction.A case was presented with the aim of showing the elements used for the diagnosis and treatment of the pulmonary edema due to negative pressure. An ASA I, 7-year-old female patient, was operated on a functional metatarsus varus with balanced general anesthetic and classical laryngeal mask number 3. She developed this adverse event during the anesthetic recovery. The diagnosis was based on the thoracoabdominal dissociation when recovering spontaneous ventilation, crepitation in hemithoraxes, central cyanosis, hypoxemia, and alveolar bilateral diffused infiltrate. The trachea was intubated, ventilation was controlled with positive pressure at the end of the expiration and furosemide was administered. The patient was transferred to the Intensive Care Unit where she evolved satisfactorily. This is a syndrome whose true incidence is unknown as a result of the lack of familiarization with it. Patients' evolution is favorable whenever the right diagnosis and treatment are timely established (AU).

Objective To investigate the clinical values of dexmedetomidine in general anesthetic for laparo-scopic cholecystectomy.Methods One hundred patients admitted to our center with cholelithes were prospectively studied.According to the principle of completely random digital table,all patients were randomly signed to dexmedeto-midine group or control group.The primary outcomes were hemodynamic changes and postoperative complications. Results There was no significant differences at t0,t1,t2,t3,t4 and t5 in mean arterial pressure (P >0.05).There was no significant difference in heart rate at t0 (P =0.503),however,compared with the control group,patients in the dexmedetomidine group got a significant reduction in t1,t2,t3,t4 and t5 in heart rate(all P 0.05 ).Conclusion Dexmedetomidine contributed to maintaining the hemodynamic stable in general anesthetic for laparoscopic cholecystectomy,and reducing the rate of shivering.
RESUMEN
Anesthetics can affect the structure and biological function of tissues and systems differentially. The aim of the present study was to compare three injectable anesthetics generally used in experiments with animals in terms of the degree of hemolysis and glycogenolysis occurring after profound anesthesia. Twenty-four male Wistar rats (330-440 g) were divided into three groups (N = 8): chloral hydrate (CH), ketamine + xylazine (KX), Zoletil 50® (zolazepam and tiletamine) + xylazine (ZTX). After deep anesthesia, total blood was collected. The liver and white (WG) and red gastrocnemius (RG) muscles were also immediately removed. The degree of serum hemolysis was quantified on the basis of hemoglobin concentration (g/L). Hepatic and muscular glycogen concentrations (mmol/kg wet tissue) were quantified by the phenol-sulfuric method. The CH and KX groups exhibited serum hemolysis (4.0 ± 2.2 and 1.9 ± 0.9 g/L, respectively; P < 0.05) compared to the ZTX group, which presented none. Only KX induced elevated glycogenolysis (mmol/kg wet tissue) in the liver (86.9 ± 63.2) and in WG (18.7 ± 9.0) and RG (15.2 ± 7.2; P < 0.05). The CH and ZTX groups exhibited no glycogenolysis in the liver (164.4 ± 41.1 and 176.8 ± 54.4, respectively), WG (28.8 ± 4.4, 32.0 ± 6.5, respectively) or RG (29.0 ± 4.9; 25.3 ± 8.6, respectively). Our data indicate that ZTX seems to be an appropriate general anesthetic for studies that seek to simultaneously quantify the concentration of glycogen and serum biochemical markers without interferences. ZTX is reasonably priced, found easily at veterinary markets, quickly induces deep anesthesia, and presents a low mortality rate.
