Brief Summary

The Cesarean Section (C/S) rate from 1970 to 2007 in U.S is 31.8% and in Iran From 2000 to 2009 rose to 50-65%. This Surgical Procedure is not without risk. Difficult head Extraction in C/S occur in 1-2% of all deliveries. This study was designed to compare the results of delivery by vacuum in C/S with normal caesarean section.

Outcome Measures

Primary Outcomes (1)

  • Mean duration time between incision and fetal head delivery

    In study was done by Arad et al in 1986, duration between incision and end of delivery was significantly lower in vacuum group that (PMID: 3735047). Also in study of Dimitrov et al was done prospectively on 19 caesarean with vacuum and 25 caesarean without it, similar results has been reported (PMID: 18756824).

    during surgery

Secondary Outcomes (1)

  • fetal complications

    after extraction of fetus and during cleaning of fetus under warmer

Other Outcomes (1)

  • maternal complications

    during surgery and first hour after childbirth (after extraction of fetus when surgeon wanted to correct the lesions)

Study Arms (2)

vacuum

EXPERIMENTAL

Vacuum is an instrument that is using for helping delivery when there is no possibility of spontaneous delivery. First report of using vacuum was in 1962 by Solomon for delivery of fetal head. He suggested that using this instrument will lower pressure on fetal head and decrease delivery time (and then decrease fetal hypoxemia). Also it decreases spreading of incision and vascular injury (during manual maneuvers).

Procedure: vacuum

routine manual maneuvers for fetal head extraction

EXPERIMENTAL

Procedure/Surgery: fetal head techniques like fundal pushing, pulling technique or reverse breech extraction

Procedure: routine manual maneuvers for fetal head extraction

Interventions

vacuumPROCEDURE

Vacuum is an instrument that is using for helping delivery when there is no possibility of spontaneous delivery. First report of using vacuum was in 1962 by Solomon for delivery of fetal head (12). He suggested that using this instrument will lower pressure on fetal head and decrease delivery time (and then decrease fetal hypoxemia). Also it decreases spreading of incision and vascular injury (during manual maneuvers). Some studies confirmed these results (13, 14) and some others disagreed it (15, 16). Considering with importance of fetal head delivery in a short time during C/S and to decrease maternal complications like lacerations and vascular injuries, this study was designed to compare the results of delivery by vacuum in C/S with routine methods for head extraction during difficult caesarean sections.
