BACKGROUND AND OBJECTIVES The transversus abdominis plane (TAP) block has been shown to provide analgesia for lower abdominal wall incisions. We evaluated the efficacy of the TAP block for post-cesarean delivery (CD) patients used as a part of a multimodal regimen. METHODS Women undergoing elective CD under spinal anesthesia were randomized to receive the(More)
BACKGROUND When diagnosed antenatally placenta accreta has often been managed by cesarean hysterectomy, but recently techniques involving uterine preservation have been developed. Uterine artery embolization has become an adjuvant treatment, although the potential for obstetric hemorrhage still exists. A multidisciplinary approach has permitted the(More)
OBJECTIVES The purpose of this study was to determine the frequency of perineal pain in the 6 weeks after vaginal delivery and to assess the association between perineal trauma and perineal pain. Study design This was a prospective cohort study of parturients at 1 day, 7 days,' and 6 weeks' post partum in an academic tertiary obstetric unit in Toronto,(More)
PURPOSE We sought to determine the incidence, etiology, characteristics and risk factors for all headaches in the first week postpartum. METHODS This was a prospective cohort study of 985 women delivering over a three-month period in a single tertiary-care institution. These women underwent a structured interview and follow-up to collect demographic data(More)
BACKGROUND Palpation has been shown to be inaccurate at identifying lumbar interspinous spaces. Our goal in this study was to compare ultrasound imaging of the region to palpation. METHODS Using ultrasound in the postpartum period, we estimated the interspinous level used for obstetric neuraxial anesthesia in 121 women and compared this estimation with(More)
The ability of a recombinant Streptococcus gordonii RJM4 expressing the N-terminal 179-amino acid fragment of S1 subunit of pertussis toxin (PT) as a SpaP/S1 fusion protein was tested for oral colonization and immunogenicity in BALB/c mice. Following two consecutive oral inoculations, 100% of the mice were colonized by the recombinant strains for up to 9(More)

DESIGN Prospective cohort study with follow up at one day, seven days, and six weeks after delivery. SETTING Teaching hospital in Montreal. SUBJECTS 329 women who delivered a live infant(s) during the study period. Exclusion(More)
OBJECTIVE The purpose of this study was to evaluate the incidence of peripartum myocardial ischemia in Canada. STUDY DESIGN We identified the cohort of women who were admitted to Canadian hospitals for delivery between 1970 and 1998 to calculate the incidence rate and to evaluate potential risk factors. RESULTS One hundred fourteen of 10,032,375 women(More)
