AbstractHiccups, or singultus, are the result of spontaneous and repetitive contractions of the diaphragm. In most cases, episodes of singultus are benign and self-limited. However, prolonged attacks can result in significant discomfort, morbidity, and even death. Although the etiology of hiccups is theoretical at best, a wide array of treatments has been proposed with varying efficacy. Both pharmacologic and nonpharmacologic treatments target different components of the hiccup reflex, which includes the vagus and phrenic nerves, the respiratory center in the upper medulla, and the motor neurons in the diaphragm, glottis, and external intercostal muscles. In this case report, we describe the successful cessation of hiccups in a 9-year-old boy with a treatment called suboccipital release. With this approach, gentle traction and pressure is applied to the posterior neck, stretching the suboccipital muscles and fascia. The manual decompression of the vagus, and possibly phrenic, nerves interrupts the hiccup reflex and allows for normal autonomic function to be reestablished. We propose that the suboccipital release, noninvasive, simple, and with virtually no side effects, is an ideal initial treatment of singultus.
