[Manual intrauterine aspiration using a Karmann syringe. Multicenter study in Sonora and Sinaloa, Mexico]

These are the results of a prospective, multicentric study carried out in five institutional hospitals in Sonora and Sinaloa, using Karmann syringe and cannulae for manual intrauterine aspiration in cases of incomplete abortion, dead and retained ovum, hidatiform mola and endometrial biopsy. Management data in 1046 patients, are described; methodology is shown, and demonstrating that it converts uterine emptying is a simple, efficacious and economical procedure, with a very low risk and it allows these patients management in an ambulatory way. From these results, and as it is demonstrated in the study, institutions may increase their programable resources as to amount of disposable beds, for other type of patients, and the offering of attention by surgeon, anesthetist, nurse and medication, as their hospital stay is minimal, and in most of the cases active anesthetist participation is not required. In the same way, it permits the patient a better relationship with the personal of the institution, and so, a more human care and the possibility of reintegrating the patient to a familiar environment, rapidly, and in good psychical and physical conditions.
