INTRODUCTION

Hysteroscopy is the gold standard procedure for the evaluation and diagnosis of intrauterine pathologies. The optimal time to do hysteroscopy is during the proliferative phase. However, for women with irregular bleeding, the optimal time is unpredictable. Besides pharmacological means, mechanical endometrial preparation could be done.

The objective of this study was to determine the effect of suction curettage on visualization, operative time, fluid deficit, and histopathologic diagnosis among perimenopausal women with abnormal uterine bleeding (AUB) and unprepared endometrium prior to operative hysteroscopy.

Thirty-four (34) perimenopausal women admitted for AUB with unprepared endometrium for operative hysteroscopy who consented to participate were recruited and randomly divided into two groups: 18 women had suction curettage done prior to operative hysteroscopy and 16 women had operative hysteroscopy done alone. The following data were obtained for each group: (1) improvement in clarity (i.e., visualization of fundus and both tubal ostia), (2) operative time from entry to withdrawal of the resectoscope (measured in minutes), (3) fluid deficit, and (4) final histopathological diagnosis. P 

Women who underwent suction curettage prior to operative hysteroscopy had improved visualization (72.2%, P < 0.001), shorter operative time (29.06 ± 7.06 min vs. 35.5 ± 7.2 min, P = 0.013), no difference in fluid deficit (P = 0.276), and the histopathologic diagnosis (P = 0.470).

Suction curettage prior to operative hysteroscopy among perimenopausal women with AUB and unprepared endometrium improved visualization and shortened operative time without affecting fluid deficit and histopathologic diagnosis.

OBJECTIVES: To study the feasibility of tracheal intubation for meconium suction immediately after birth of nonvigorous neonates born through meconium-stained amniotic fluid (MSAF). METHODS: A retrospective cohort study was performed on nonvigorous neonates born through MSAF who were admitted to the Department of Neonatology, Zhecheng People's Hospital. The neonates without meconium suction who were admitted from July 1, 2017 to June 30, 2018 were enrolled as the control group. The neonates who underwent meconium suction from July 1, 2018 to June 30, 2019 were enrolled as the suction group. The two groups were compared in terms of the mortality rate and the incidence rates of neonatal meconium aspiration syndrome (MAS), persistent pulmonary hypertension of the newborn, pneumothorax, and pulmonary hemorrhage. RESULTS: There were 80 neonates in the control group and 71 in the suction group. There were no significant differences between the two groups in the incidence rates of MAS (11% vs 7%), persistent pulmonary hypertension of the newborn (5% vs 4%), pneumothorax (3% vs 1%), and death (0% vs 1%). Compared with the control group, the suction group had a significantly lower proportion of neonates requiring oxygen inhalation (16% vs 33%, P<0.05), noninvasive respiratory support (25% vs 41%, P<0.05) or mechanical ventilation (10% vs 23%, P<0.05) and significantly shorter duration of noninvasive ventilation [(58±24) hours vs (83±41) hours, P<0.05] and length of hospital stay [6(4, 8) days vs 7(5, 10) days, P<0.05]. CONCLUSIONS Although tracheal intubation for meconium suction immediately after birth may shorten the duration of respiratory support for mild respiratory problems, it cannot reduce the incidence rate of MAS, mortality rate, or the incidence rate of serious complications in nonvigorous infants born through MSAF.

Objective: To introduce a new self-developed irrigation device(SID) that does not employ a sheath or an irrigation-suction system and evaluate to its efficiency in transcanal endoscopic ear surgery (TEES) for attic cholesteatoma. Methods: 38 patients who were subjected to TEES for attic cholesteatoma between October 2019 to June 2021 were included in this study, including 17 males and 21 females with an average age of (38.6±11.9) years. SID and underwater continuous drilling were used during operation. Width of endoscope and irrigation speed were measured when SID was applied. The operating time, surgical view and complications were compared between two groups. Results: The width of the endoscope was 3.5-4.6 mm in diameter and the irrigation speed was 20-40 ml/min when SID was used. SID cleaned the lens at the tip of the endoscope and created a clear field of view during TEES. The operation time was (86.6±18.1) min. The skin of the external ear canal was found injured during operation in 3 patients, but there were no complications such as necrosis of the flap, stenosis of external ear canal, sensorineural hearing loss, facial paralysis and cerebrospinal fluid leakage. Conclusions: SID is simple and enhances the efficacy of TEES, providing a new irrigation choice in TEES for attic cholesteatoma.

Endotracheal suctioning is a most frequent invasive procedure in neonates undergoing mechanical ventilation. The procedure includes the patient preparation, airway suctioning and follow-up care, which may associated with adverse events. Based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE), as well as the related research both in China and overseas, the clinical practice guidelines of endotracheal suctioning in neonates with mechanical ventilation is developed in order to promote the standard implementation of this operation and ensure patients' safety.

According to the actual requirements of pediatric intensive care, a suction detection system of pediatric oral secretions integrated with monitoring function is designed. The system has the function of adjustable intermittent attraction. The duration and proportion of intermittent attraction can be adjusted according to the individualized needs of pediatric intensive care. The suction head of pacifier can reduce the mechanical damage to pediatric oral mucosa as much as possible. Meanwhile, the system can detect and monitor the real-time biochemical indexes of the collected oral secretions, which can be used to help the judgement of aspiration and quantitatively evaluate the microcirculation dysfunction.

PURPOSE: Despite the long history of drain use in total knee arthroplasty (TKA), no drain has been gaining popularity. The purpose of this study was to investigate whether drainage is related to the length of hospital stay. MATERIALS AND METHODS: A total of 166 consecutive unilateral TKAs performed on 135 patients with osteoarthritis were retrospectively reviewed. Closed suction drainage was used in 111 cases (67%). Length of hospital stay after surgery was recorded, and a multivariate linear regression analysis was performed to evaluate various variables (patient factors, surgical factors, and post-surgical factors) and to investigate whether drainage was an independent variable. RESULTS: Hospital stay was shorter in no drain cases (21.7±4.8 days) than in drain cases (24.2±3.7 days, p<0.001). The multivariate analysis showed that older age (β=0.12, p=0.02), drain use (β=2.81, p=0.03), and occurrence of comorbidity (β=1.46, p=0.04) were the independent variables associated with the extended hospital stay. There was no difference in comorbidity between drain cases (39.6%) and no drain cases (27.2%, p=0.13). CONCLUSIONS: The drain use, age, and occurrence of comorbidity were related to the length of hospital stay. TKA without drain is an effective procedure both medically and economically.

BACKGROUND: Postoperative suction drains are used after total knee arthroplasty to avoid intra-articular hematoma formation although they can increase blood loss due to a negative suction effect. The use of tranexamic acid to reduce blood loss may nullify this. The aim of this study was to compare outcomes in patients undergoing total knee arthroplasty with or without drains and to analyze whether the drain's diameter also has an impact. METHODS: This is a prospective randomized study of patients undergoing unilateral total knee arthroplasty performed by a single surgeon. The study population was divided into three groups (A, 10G drain; B, 12G drain; and C, no drain). Pain, blood loss, swelling, wound-related complications, functional outcomes and questionnaire-based outcomes were assessed postoperatively. RESULTS: Each group had 35 patients comparable in most demographic and pre- and intraoperative characteristics. During the first 6 hours postoperatively, opioid consumption was significantly higher when the drain was not used (p = 0.036). At 3 months postoperatively, new Knee Society Score (NKSS) was highest with the use of 12G drain (p = 0.018). However, NKSS at 1 year was comparable across the three groups. With the use of tranexamic acid, blood loss and incidence of soakage of dressing were unaffected by the presence or absence of a drain. The calf girth, suprapatellar girth, soakage of dressing and range of motion were comparable in all three groups. There was no incidence of surgical site infection or deep vein thrombosis. CONCLUSIONS: Presence of a suction drain significantly reduces opioid consumption during the first 6 hours after total knee arthroplasty. Use of a drain made no difference to the functional outcome at 1 year postoperatively. With the use of tranexamic acid in total knee arthroplasty, the total blood loss and the requirement of blood transfusion were unaffected by the presence or absence of closed suction drainage or by the bore of the drain used. The clinical parameters such as swelling, range of motion, infection and deep vein thrombosis also remained the same.

In patients with severely resorbed alveolar bone, it is difficult to gain retention in denture. Lack of retention makes denture unstable and lead to trouble in using denture. Suction denture seals the entire denture border with movable mucosa and this sealing mechanism forms negative pressure beneath the denture and produce higher retention and stability to denture. In this case, 4 edentulous patients visited for lack of retention with dentures. Considering their high expectation with retention, suction denture concept was used to fabricate retentive and stable denture. The purpose of this case report is to compare and analyze the considerations of suction denture restorations in edentulous patients.
