Objective: Hydrocephalus is inherently unpredictable. Most parents whose child is diagnosed with hydrocephalus do not anticipate the diagnosis, nor can anyone predict if or when a child's shunt will fail and require emergency surgery. Previous research has shown that children with hydrocephalus and their caregivers experience significant posttraumatic stress symptoms secondary to the diagnosis.

July 20, 2021 marked the 30th anniversary of the publication of the landmark trial by the British Medical Research Council showing unequivocally that maternal intake of folic acid (vitamin B) starting before pregnancy prevents most cases of infant spina bifida and anencephaly-two major neural tube defects that are severe, disabling, and often fatal. Mandatory food fortification with folic acid is a safe, cost-effective, and sustainable intervention to prevent spina bifida and anencephaly. Yet few countries implement fortification with folic acid; only a quarter of all preventable spina bifida and anencephaly cases worldwide are currently avoided by food fortification.

Background: Improvements in antenatal medicine and surgical management for conditions associated with spina bifida such as hydrocephalus have extended the lifespan for individuals with spina bifida (SB) into adulthood. Decisions and education regarding reproductive care and pregnancies for patients with spina bifida are increasingly important. Pregnancy in these patients can be particularly challenging due to physical limitations, previous abdominal surgery for urinary or bowel management and presence of a ventriculoperitoneal shunt.

Objective: Hydrocephalus is a disorder of cerebrospinal fluid dynamics, traditionally treated by placement of a ventricular shunt. Shunts are effective but imperfect as they fail in an unpredictable pattern, and the patient's well-being is dependent on adequate shunt function. The omnipresent threat of shunt failure along with the potential need for invasive investigations can be stressful for patients and caregivers.

Article Synopsis
  • International standards for safe anesthesia care have been established by the WFSA and WHO, but their implementation in Guatemala, despite universal health coverage, is unclear.
  • A national survey in 2018 assessed anesthesia care in 36 public surgical hospitals using the WFSA anesthesia facility assessment tool, focusing on various factors like infrastructure, workforce, and medication availability.
  • The findings revealed a low density of anesthesia providers, with only 10% of district hospitals having continuous anesthesia presence during surgeries, and although some medications were readily available, essential ones like ketamine and epinephrine were lacking in several hospitals.
