The nursing experience of a pregnant woman with stillbom fetus with a septic shock to cardiac arrest at 30 weeks of pregnancy was summarized.The critical points of nursing include first aid nursing of cardiac arrest during pregnancy,preparation of transport plan to ensure ECMO combined with CVVH to support cesarean section,anti-infection nursing of fetal death complicated with septic shock,precise implementation of target temperature management,individualized anti-coagulation nursing under multiple factors interference.After 31 days of careful treatment and nursing,the patient's condition was stable,discharged smoothly,and the patient recovered well after 5 months of follow-up.

Objective:To evaluate the efficacy of ultrasound-guided superior laryngeal nerve block(SLNB) combined with intravenous anesthesia for improving pediatric fiberoptic bronchoscopy.Methods:Forty pediatric patients of either sex, aged 3-6 yr, of American Society of Anesthesiologists Physical Status classificationⅠor Ⅱ, with body mass index of 18-24 kg/m 2, undergoing fiberoptic bronchoscopy in Cangzhou Central Hospital in 2022, were divided into 2 groups ( n=20 each) by a random number table method: ultrasound-guided SLNB plus intravenous anesthesia group (group A) and topical anesthesia plus intravenous anesthesia group (group B). After sedation with dexmedetomidine and esketamine, ultrasound-guided bilateral SLNB was performed with 1% lidocaine 0.5 ml (for each side)in group A, and topical anesthesia was performed with 1% lidocaine in nasal and pharyngeal cavities in group B. After completion of the surgery procedure, propofol was continuously infused at 5 mg·kg -1·h -1 until completion of diagnosis and treatment. An increment of propofol 1 mg/kg was intravenously given if severe bucking or body movement occurred during operation. Mean arterial pressure (MAP), heart rate (HR) and SpO 2 were recorded on admission to the operating room (T 0), immediately after sedation (T 1), immediately after bronchoscopy entering the glottis (T 2), 5 min after start of treatment (T 3) and at the end of examination (T 4). The occurrence of intraoperative hypoxemia, HR <60 bpm, and MAP <50 mmHg were recorded, and the additional dose of propofol was recorded. The venous blood samples were collected at T 0 and T 4 to determine plasma cortisol concentrations by chemiluminescence.The surgeon′s satisfaction score was recorded. The complications of SLNB were also recorded within 2 h after operation in group A. Results:Compared with group B, HR was significantly decreased at T 2 and T 3, SpO 2 was increased, the intraoperative additional dosage of propofol and incidence of hypoxemia were decreased, and the surgeon′s satisfaction score was increased, and the concentrations of cortisol were decreased at T 4 in group A ( P<0.05). No HR<60 bpm and MAP<50 mmHg were found in two groups. No SLNB-related complications were observed after operation in group A. Conclusions:Ultrasound-guided SLNB combined with intravenous anesthesia is safer for pediatric fiberoptic bronchoscopy and can improve the analgesic effect and is more helpful in inhibiting intraoperative stress responses when compared with conventional anesthesia.

Objective:To investigate the clinicopathological characteristics of acidophil stem cell pituitary neuroendocrine tumors (PitNET)/adenoma.Methods:Five cases of acidophil stem cell PitNET/adenoma were diagnosed between May 2022 and July 2023 at the Second Hospital of Hebei Medical University, Shijiazhuang, China. The clinicopathological features of the tumor were analyzed by using histology, immunohistochemistry, and electron microscopy. The relevant literature was reviewed.Results:There were 1 male and 4 females, aged from 23 to 69 years. Patient 3 was 55 years old at the time of diagnosis and first surgery, and relapsed 5 years later. The patients′ median age was 32 years. Patients 1 and 5 showed elevated blood prolactin, with various degrees of hormonal symptoms except Patient 3, who showed only tumor compression symptoms. Imaging studies showed that all cases involved the sellar floor. The tumors of Patients 1, 2 and 5 were closely related to the cavernous sinus segment of the internal carotid artery. The tumors exhibited a diffuse growth pattern with chromophobic to slightly acidophilic cytoplasm. A few of tumor cells showed chromophobic cytoplasm. The nucleoli were conspicuous. Intranuclear inclusion bodies and variably-sized clear vacuoles were observed occasionally. Under electron microscope, marked mitochondrial abnormalities were observed, including increased mitochondria number, expanded hypertrophy, and absence of mitochondrial ridge fracture. Some mitochondrial matrices were dense, while some were vacuolated.Conclusions:Acidophil stem cell PitNET/adenoma is a rare type of pituitary adenomas/PitNETs. It often has a more clinically aggressive manner with immature cells, diffuse expression of PIT1, prolactin, and varying degrees of growth hormone expression. Because of the obvious diversity of their clinical hormone status and hormone immune expression, the diagnosis of this type tumor is still a challenge.
