The most common form of sleep apnea is obstructive sleep apnea (OSA). It is characterized by the cessation of nasal airflow with persistence of ventilatory effort, as shown by paradoxical chest and abdominal movement, and varying degrees of oxygen desaturation. This article describes current methods of diagnosing OSA and available treatment for OSA and snoring.

This study was performed to determine if intraoperative local anesthesia improved control of postoperative pain after inguinal herniorrhaphy and to compare the effects of two commonly used local anesthetics on pain management. The Gate Control Theory of Pain formed the theoretical basis for this study. A retrospective nonexperimental study in an ex post facto design was used. ⋯ Bupivacaine was found to be superior to lidocaine in decreasing the need for postoperative narcotic analgesia. Researchers concluded that many patients would benefit from intraoperative injection of local anesthesia. This information can affect patient care outcomes through decreasing recovery time, reducing postoperative pain, and reducing health care costs.

Despite advances in anesthetic technique and technology, intraoperative awareness continues to occur with alarming regularity. The psychological effects on patients and the medicolegal consequences to providers have created the need for a reliable monitor of the hypnotic component of anesthesia. A new technology known as bispectral analysis (BIS) has the potential to put an end to the devastating occurrence of intraoperative awareness, as well as improve the overall effectiveness of anesthetic delivery and the surgical experience. Applicable to almost any situation requiring sedation or general anesthesia, BIS's reliability is a real-time measure of hypnosis levels.
