title: Transverse arrest: a review of outcomes of rotational forceps and cesarean delivery at a single center.
abstract: Objective: To assess whether Kielland forceps rotational delivery causes a significant increase in maternal or perinatal morbidity in comparison with cesarean delivery in the clinical situation of transverse arrest. Rotational forceps delivery has been reported to have unacceptably high maternal and neonatal complication rates when compared with either spontaneous vaginal delivery or non-rotational forceps delivery. Clinically, however, we considered the more relevant comparison between Kielland rotational forceps delivery and cesarean delivery as these are generally the two modes of delivery for the fetus in transverse arrest.Study Design: The charts of all the mothers delivered by Kielland forceps or cesarean delivery for the main indication of transverse arrest between July 1995 and June 1996 were reviewed. The following were evaluated: Apgar scores at 1 and 5 minutes, cord pH, birth weight, neonatal superficial facial laceration or bruising, bone or nerve injuries, maternal injuries, 3rd and 4th degree perineal or vaginal lacerations, post-partum fever. Statistical analysis was by chi(2) (for Apgar scores), two-tailed Fisher Exact test (for post-partum fever), and t test (for birth weight and cord pH). A P value <.05 was considered statistically significant.Results: Fifty-two Kielland forceps and 30 cesarean deliveries were performed. One-minute Apgar scores of less than or equal to 7 were noted in 11.5% and 6.7% of the forceps and cesarean section groups, respectively (P = NS); mean arterial cord pH was 7.26 for both groups; no cases of post-partum fever were noted in the forceps versus 16% in the cesarean group (P <.05); the mean weight was 3,316 and 3,569 g for the forceps and cesarean group, respectively (P <.05). The Kielland group was also characterized by the following: 19 facial bruising and 2 temporary facial nerve injury (resolved by the time of discharge), 3 perineal lacerations, and 3 vaginal tears. No blood transfusions were required for either group.Conclusions: To our knowledge, this is the first study that compares rotational forceps delivery for transverse arrest with its true clinical alternative, cesarean delivery.No significant difference in cord pH and Apgar scores were noted between the two groups. The birth weight was greater and post-partum fever was more common in the cesarean section group. Neonatal facial bruising, temporary facial nerve palsy, and maternal perineal and vaginal lacerations were more common in the forceps groups. This study suggests that rotational forceps may be a reasonable alternative to cesarean delivery in the management of transverse arrest.
