Esophageal spasm causes severe retrosternal pain and discomfort at times. Patients with achalasia cardia, esophageal reflux, and esophageal ulcers suffer a lot for this intractable pain. The antispasmodics, calcium-channel blockers, proton-pump inhibitors, tricyclic antidepressants, and opioids are recommended as the remedies to relief this pain. Phosphodiesterase inhibitor-5 is also reported to relief this symptoms. We used almost all the optional agents on three of our patients with esophageal spasm in the postanesthesia care unit but did not get desired effects. Then, we switched over to administer intravenous nalbuphine, and we got excellent results out of it.
| Case Reports|| |
A 53-year-old female was reported with severe retrosternal pain with repeated melena for 20 h. She was found to be very anxious, restless, and severely anemic. Hence, blood transfusion was started, and an emergency upper gastrointestinal (GI) tract endoscopy was done. There was an anomalous dilated longitudinal vein along the luminal wall of the lower one-third of the esophagus with multiple ulcerations, from which there was oozing of blood [Figure 1]. The patient was excluded of having cirrhosis, chronic viral hepatitis, or portal hypertension. She was then treated conservatively with infusions of vasopressin, proton-pump inhibitors, calcium-channel blockers, and antispasmodic agents. Varieties of opioids including morphine, pethidine, and fentanyl were also tried to relieve her retrosternal pain along with imipramine. Yet, the symptoms were not relieved satisfactorily. However, we found excellent result instantaneously while used intravenous nalbuphine.

A 58-year-old male with severe retrosternal pain and melena was received. He was a known case of achalasia cardia. There was bleeding from a large organized blood clot observed endoscopically in the luminal wall of the lower third of the esophagus. This patient was also attempted with all conventional analgesics and antispasmodics but relieved significantly when we used intravenous nalbuphine.
A 31-year-old female developed severe peritonitis following hysterosalpingography with dye for investigation of her primary sterility. Within hours, she suffered from severe dyspepsia and intractable retrosternal pain due to esophageal spasm. Her upper GI endoscopy revealed normal, but she was a known case of gastroesophageal reflux disease. This patient was also tried with varieties of antispasmodics and analgesics, but there was a remarkable relief of symptoms following intravenous administration of nalbuphine.
Initially, we used 5 mg of nalbuphine intravenously, and then, we added 5 mg as increment at an interval of 15 min up to a total of 20 mg within 1 h. The possible mechanism of relaxation and analgesia may be explained by the direct actions of opioids on the opioid receptors (i.e., mu, kappa, and delta) in enteric neurons of esophagus [Figure 2]. When the esophageal receptors are activated, the propulsive activity, secretions, and peristalsis decrease, resulting relaxations and analgesia as well. Moreover, the agonist-antagonists causes fewer adverse effects of pure agonist opioids such as nausea, constipation, and biliary spasm.
The patients experienced a little drowsiness and sweating for a while just after administration of the drug and following that, there were no other complications which conforms to other reports. The respiration and hemodynamics were stable. These reports show that intravenous nalbuphine has a significant role on relieving retrosternal pain due to esophageal spasm when other remedies failed. Our limitations were – we did not perform and monitor the esophageal manometry and the pain scoring system. Large-scale studies are recommended to advocate the routine use of nalbuphine for the relief of esophageal spasmodic pain.
