Ileal or cecal segments may be problematic because of a shorter mesentery, which may produce tension on the neovagina, leading to stenosis. The sigmoid neovagina is thought to be self-lubricating, without the excess mucus production associated with segments of small bowel. Vaginoplasty may create scarring at the introitus (the vaginal opening), which requires additional surgery to correct. Vaginal dilators are required postoperatively to prevent vaginal stenosis from scarring. Inflatable vaginal stents are placed in the vagina deflated and then gently inflated. Other complications include bladder and bowel injuries. Yearly exams are required as neovaginoplasty carries a risk of carcinoma, although carcinoma of the neovagina is uncommon. Neither neovaginoplasty nor vaginal dilation should be performed before puberty. Prognosis
Challenges presented to people affected by this condition include: psychologically coming to terms with the condition, difficulties with sexual function, infertility. Long-term studies indicate that with appropriate medical and psychological treatment, women with CAIS can be satisfied with their sexual function and psychosexual development. CAIS women can lead active lives and expect a normal lifespan. Epidemiology
It is estimated that CAIS occurs in 1 in 20,400 to 1 in 99,000 individuals with a 46,XY karyotype. Nomenclature
Historically, CAIS has been referred to in the literature under a number of other names, including testicular feminization [syndrome] (deprecated) and Morris syndrome. PAIS has also been referred to as Reifenstein syndrome, which should not be confused with CAIS. History
The first definitive description of CAIS was reported in 1817.
When midazolam is administered in combination with fentanyl, the incidence of hypoxemia or apnea becomes more likely.Although the incidence of respiratory depression/arrest is low (0.1–0.5%) when midazolam is administered alone at normal doses, the concomitant use with CNS acting drugs, mainly analgesic opiates, may increase the possibility of hypotension, respiratory depression, respiratory arrest, and death, even at therapeutic doses. Potential drug interactions involving at least one CNS depressant were observed for 84% of midazolam users who were subsequently required to receive the benzodiazepine antagonist flumazenil. Therefore, efforts directed toward monitoring drug interactions and preventing injuries from midazolam administration are expected to have a substantial impact on the safe use of this drug. Pregnancy and breastfeeding
Midazolam, when taken during the third trimester of pregnancy, may cause risk to the neonate, including benzodiazepine withdrawal syndrome, with possible symptoms including hypotonia, apnoeic spells, cyanosis, and impaired metabolic responses to cold stress. Symptoms of hypotonia and the neonatal benzodiazepine withdrawal syndrome have been reported to persist from hours to months after birth. Other neonatal withdrawal symptoms include hyperexcitability, tremor, and gastrointestinal upset (diarrhea or vomiting). Breastfeeding by mothers using midazolam is not recommended. Elderly
Additional caution is required in the elderly, as they are more sensitive to the pharmacological effects of benzodiazepines, metabolise them more slowly, and are more prone to adverse effects, including drowsiness, amnesia (especially anterograde amnesia), ataxia, hangover effects, confusion, and falls.
