The newest safest pain control option is now available at The Birth Center of New Jersey. Nitrous Oxide Patient Controlled Analgesia can help relax you and reduce your pain during labor and the cost is 4 or 5 times less than an epidural without the side effects. This system can be used anywhere, even during a water birth and during any stage of labor without slowing it down. Single-use disposable masks or mouthpieces for your safety and comfort are provided.
