Experiences implementing hydrocolloid dressings after caesarean section.

AIM: Despite increasing interest in reduction of surgical site infection (SSI) after caesarean section, there is limited evidence around optimal dressing choice. We report the experience of a secondary hospital in regional New Zealand changing from a basic contact dressing to a hydrocolloid dressing over a three-month period, reporting SSI rates, midwifery and nursing experience, and cost. METHOD: A retrospective cohort study of hydrocolloid dressings for caesarean sections over three months, compared with basic contact dressings in caesarean sections in the same period one year previously. We report wound swabs with significant growth; results from a survey sent to midwifery and nursing staff; and cost per dressing, as well as the number of dressing changes before discharge. RESULTS: In the hydrocolloid group (n=94) four patients had significant growth on wound swabs (4.3%, 95% confidence interval (CI): 0-10.6%) compared with six patients in the basic contact group (n=117) (5.1%, 95% CI: 1.0-7.1%). Only 9/20 (45%) midwives reported that they liked the hydrocolloid dressings, compared with 19/21 (90%) liking the basic contact dressings, primarily due to difficulty removing the dressings. When accounting for the number of dressing changes on the ward, the cost per caesarean section was $5.11 NZD for hydrocolloid dressings, compared with $5.72 NZD for basic contact dressings. CONCLUSION: Our initial experience with a change to hydrocolloid dressings showed promising results with regard to SSI rates, as well as a cost reduction. This, however, is to be balanced with dressings that are potentially more difficult to remove, resulting in reduced midwifery and nursing satisfaction.

Caesarean scar ectopic pregnancy: a case series and case report to highlight the experience in regional New Zealand.

AIMS: To evaluate the approach to diagnosis and management of caesarean scar pregnancy (CSP) at a regional New Zealand hospital. METHODS: A retrospective case series of ten patients between June 2015 and May 2020. The data review included demographic information, ultrasound findings, human chorionic gonadotropin (HCG) levels, primary and subsequent treatment, outcomes and complications. RESULTS: Nine women were diagnosed with CSP at a gestational age between four and ten weeks. One of these women was treated twice for two separate CSP within the study period. Treatment varied according to clinical presentation, HCG levels, gestational age, ultrasound findings and patient preference. Two thirds of women were successfully treated with primary management, with one third requiring multiple treatment modalities. We report one severe life-threatening haemorrhage and three cases resulting in hysterectomy. We also show a disproportionate number of Maori women presenting with CSP. CONCLUSION: We present a series of ten cases of CSP and demonstrate similar challenges in regional New Zealand to those reported elsewhere. Management is heterogeneous with little guidance from the literature, and primary management was successful in seven out of ten cases. We report a disproportionately high number of cases in Maori women. Our results would support the development of a national register for caesarean scar pregnancy to improve diagnosis and management across New Zealand.

Five-year follow-up after cervical cytology and histology discordance: A retrospective cohort study.

BACKGROUND: Cervical smear cytology and colposcopic biopsy histology are prone to error at both collection and interpretation stages, leading to a large number of discordant cases. AIMS: Investigation of five-year outcomes for women who have cervical cytology that is discordant and higher grade than histology results. MATERIALS AND METHODS: A retrospective cohort study was carried out for 111 women with cervical cytology discordant and higher grade than histology, after cytopathological review, over a three-year period. Five-year follow-up data were reviewed to identify the highest level of pathology seen within five years from the discordance. RESULTS: Women with atypical squamous cells with possible high-grade change (ASC-H) cytology and negative biopsy (n = 28) had a 46% chance of high-grade histological disease within 5 years; with cervical intraepithelial neoplasia grade 1 (CIN1) histology (n = 20), this was reduced to 30%. With high-grade cytology and negative histology (n = 23), 48% had high-grade disease within five years, including one case of invasive disease; with CIN1 histology 50% had high-grade disease within five years. CONCLUSIONS: This study demonstrates a 30-50% chance of high-grade disease within five years, in the setting of ASC-H or high-grade cytology with a negative or low-grade colposcopic biopsy. This highlights that in the setting of cytology and histology discordance, at least one of the tests indicating high-grade pathology warrants the need for treatment or close ongoing surveillance.
