abstract background: we aimed to evaluate an approach to induced abortions during early pregnancies that controls the suction pressure and restricts the duration of the procedure. methods: three hundred patients programmed for induced early pregnancy abortions, hospitalized in the shandong provincial maternity & child care hospital from october 2013 to october 2015, were enrolled. patients were...

OBJECTIVE To evaluate whether manual or electric vacuum aspiration results in greater immediate confirmation of completed abortion at less than 6 weeks of gestation. METHODS Five hundred pregnant women presenting for surgical abortion with mean gestational sac diameter of less than 12 mm or no visible sac on ultrasonography were randomized to manual or electric vacuum aspiration. Tissue exami...

An aspiration system, incorporating a regulated vacuum pump, was used to examine, in vitro, some factors that may affect oocyte collection. In an open aspiration system, as the length of the needle was increased, or the internal diameter decreased, the velocity (and flow rate) of aspirated fluid decreased. There was a difference, however, between experimental flows and those predicted by Hagen-...

OBJECTIVE Ectopic pregnancy in the interstitial part of the Fallopian tubes can be life-threatining considering the thin myometrial tissue surrounding the gestational sac and highly vascularization which may result in catastrophic haemorrhage when interstitium is ruptured. The diagnosis and management is challenging. Conservative, medical, and surgical treatment options should be considered bas...

BACKGROUND In vitro hemolysis can be induced by several biological and technical sources, and may be worsened by forced aspiration of blood in vacuum tubes. This study was aimed to compare the probability of hemolysis by drawing blood with a commercial evacuated blood collection tube, and S-Monovette used either in the "vacuum" or "aspiration" mode. MATERIALS AND METHODS The study population ...

Two mathematical models of vacuum aspiration, being a method widely used in various branches of medicine, are considered. In particular, vacuum aspiration is an effective method of prostatitis therapy. The purpose of vacuum aspiration in this urological procedure is to destroy the plug, which clogs up the ill acinus. We analyze plausible physical mechanisms of purification of prostatic acini an...

OBJECTIVES To investigate the use of manual vacuum aspiration in postabortion care in Malawi between 2008-2012. METHODS A retrospective cross-sectional study was done at the referral hospital Queen Elisabeth Central Hospital, and the two district hospitals of Chiradzulu and Mangochi. The data were collected simultaneously at the three sites from Feb-March 2013. All records available for women...

OBJECTIVES To assess women's preferences for, and the acceptability of, medical abortion and vacuum aspiration in the early first trimester. DESIGN Patient centred, partially randomised trial. Medical abortion was performed with mifepristone 600 mg followed 48 hours later by gemeprost 1 mg vaginal pessary. Vacuum aspiration was performed under general anaesthesia. SETTING Teaching hospital ...

BACKGROUND Nepal government has approved medical abortion and manual vacuum aspiration for early first trimester pregnancy. Both the procedures have been approved by World Health Organization for use in early first trimester. OBJECTIVES The study aims to compare efficacy and safety of medical abortion with surgical abortion in a district hospital of rural eastern Nepal. METHOD An observatio...

PURPOSE The purpose of this study was to compare needle aspiration and vacuum-assistedbiopsy in the ultrasound-guided treatment of lactational breast abscesses. METHODS Between January 2005 and December 2014, a total of 74 patients presented withlactational breast abscesses. Thirty of these patients underwent treatment with antibioticsalone, while the remaining 44 lactating women with breast ...
