Healthcare in Pakistan
Depression often starts at young age and affects women more commonly than men. One or two mothers out of 10 have depression after childbirth. Depression also limits a mother’s capacity to care for her child, and can seriously affect the child’s growth and development. A study showed that exposure to maternal mental distress is associated with undernutrition in 9‐month infants in urban Pakistan.
Pain management during childbirth
Nitrous oxide has the added benefit of limited side effects.  Some mothers may experience some dizziness, nausea, vomiting, or drowsiness, however, since dosing is determined by the patient, once these symptoms begin she can limit her use.  The gas takes effect quickly, but also lasts a short period of time so she must hold the mask to her face in order to benefit from the effects of analgesia. There is very little effect to the baby since it is quickly eliminated by the baby as soon as it begins breathing. Evidence does not suggest any clinically significant risk factors in the use of nitrous oxide gas as opposed to other methods of pain management both non-pharmacologic and pharmacologic in terms of Apgar or cord blood gas.  There is also limited evidence to determine whether there are any increased occupational risks to the healthcare provider associated with the use of nitrous oxide.
