Background Unsafe abortion is a public health problem worldwide. One way of reducing the number of unsafe procedures is to increase safe choices for pregnancy termination. In developed countries, of the 28 million pregnancies occurring every year, 36% end in abortion. In developing countries, of the 182 million pregnancies occurring every year, 20% end in abortion. Almost 80% of all abortions a...

BACKGROUND Some medical equipment manufacturers and surgeons have asserted that certain types of cannulas and other components of liposuction systems enhance the efficiency of fat aspiration. OBJECTIVE A laboratory experiment was designed to evaluate the effect of each component of a standard liposuction system on the rate of fat aspiration. A clinical investigation of the effectiveness of a ...

Holstein cow ovaries obtained at a slaughterhouse were used to study the influence of the oocyte collection methods (slicing, puncture, aspiration I and II) on recovery efficiency and subsequent in vitro maturation and embryonic development competence of immature oocytes recovered. In the slicing method, the whole ovarian was chopped into small pieces with a surgical blade. In the puncture meth...

Since circulating tumor cells (CTCs) are tumor cells which are found in the blood of cancer patients, CTCs are potential tumor markers, so a rapid isolation of CTCs is desirable for clinical applications. In this paper, a three-dimensional polystyrene (PS) microfiber fabric with vacuum aspiration system was developed for capturing CTCs within a short time. Various microfiber fabrics with differ...

PURPOSE To analyze the effectiveness and occurrence of complications, in addition to hospitalization time and blood losses. METHODS Thirty patients were assigned alternatively and consecutively to one of two groups (15 to the Curettage Group and 15 to the Manual Vacuum Aspiration Group). The following variables were analyzed: effectiveness of the method, occurrence of complications, time befo...

The development of low-traumatic surgical drains aimed at maximum possible separation blood and air, is an important trend in modern medicine. objective this work to create inexpensive, user-friendly dynamic aspiration system (DBAS). allows effective air when drawing from a wound under vacuum conditions required for aspiration. operating principle the separate liquid gas fractions blood-air mix...

Twenty nine patients with localized cutaneous leishmaniasis had lymph node and skin ulcer aspirations for culture of Leishmania with the modified Marzochís vacuum aspiratory technique. Sensitivity of lymph node aspiration was 58.6% and 34.5% for skin ulcer aspiration (P=0.06). Combined sensitivity of the two methods was 79.3%. There was no agreement between methods (Kappa Index = -0.084; CI95% ...

OBJECTIVE Pulmonary aspiration of gastric contents occurs 20 to 30% of the time during cardiopulmonary resuscitation (CPR) of cardiac arrest due to loss of protective airway reflexes, pressure changes generated during CPR, and positive pressure ventilation (PPV). Although the American Heart Association has recommended the laryngeal mask airway (LMA) as an acceptable alternative airway for use b...

Serial studies on coagulation factors were performed on 12 patients having termination of mid-trimester pregnancy by extra-amniotic prostaglandin F(2)alpha and 11 patients terminated by vacuum aspiration during the first trimester. A significant change in the activity of factors V, VII and X, VIII, and X, and a decrease of the prothrombin time and platelet count were found with prostaglandin te...

BACKGROUND Some 40% of abortions carried out in England and Wales are done by vacuum aspiration. It is widely assumed that, in order to be lawful, these procedures must be performed by doctors. AIM AND DESIGN This study aimed to provide a detailed reassessment of the relevant law and the clinical evidence that supports this assumption. CONCLUSIONS A close reading of relevant law reveals tha...
