RESUMEN
BACKGROUND: In patients who are candidates for craniotomy, scalp nerve blocks have been shown to be effective in relieving pain intensity as well as postoperative hemodynamic stability after surgery, but the results have been inconsistent. We aimed to assess the effect of scalp block on pain control, intraoperative drug use under Analgesia Nociception Index (ANI) monitoring, and postoperative pain in patients who were candidates for elective craniotomy. METHODS: In this randomized, single-blinded clinical trial study, candidates for craniotomy were randomly (using the block randomization method) divided into 2 groups before entering the operating room. The first group received a scalp block with bupivacaine (intervention), and the second group did not receive a scalp block (control) besides the routine anesthetic procedure in these patients. ANI, hemodynamic parameters, and the amounts of received remifentanil were conducted and compared. RESULTS: Patients under scalp block received less dosage of fentanyl than the nonscalp block group (mean = 57.14 ± 15.59 mcg vs. 250.00 ± 65.04 mcg, respectively). Similarly, the dose of remifentanil required in the scalp block group was less (mean = 3.04 ± 1.95 mg and 5.54 ± 2.57 mg, respectively). No difference was observed in hemodynamic parameters such as blood pressure and heart rate (before, during, and after surgery). However, the group receiving scalp block had higher ANI means than the control group. CONCLUSIONS: Scalp nerve block has an effective role in pain control (increasing ANI), consequently reducing the need for analgesic drugs such as fentanyl and remifentanil following craniotomy without changing the hemodynamic condition.
RESUMEN
Clostridium botulinum produces the most potent bacterial toxin, botulinum toxin A (BTXA), which has various therapeutic and cosmetic indications. Intragastric BTXA injection is a new obesity treatment method that was argued to be safe due to the inactivation of BTXA through the liver or metabolization within the gastric wall. However, a 36-year-old woman was admitted to the intensive care unit (ICU) due to developing botulism as a result of an intragastric injection of BTXA. The diplopia, headaches, ptosis, decreased muscle force, and respiratory distress two days after injection were her first chief complaints, and also, she experienced significant dysphagia, hoarse voice, thick tongue, constipation, hyposmia, and hypogeusia after two weeks. This case report highlights the necessity for physicians to have sufficient information about this method and consider possible life-threatening adverse effects including botulism.
RESUMEN
Generalized tetanus is still a global concern with a mortality rate of up to 50%, especially in low and middle-income countries. We reported a 23-year-old man from Afghanistan admitted to emergency department, with the chief complaint of generalized severe spasms and lockjaw. The patient had skin lesions and had never been vaccinated against tetanus. He intubated and admitted to the intensive care unit (ICU) with diagnose of severe generalized tetanus. After receiving tetanus immunoglobulin and intravenous metronidazole, a combination therapy of midazolam, propofol, atracurium, and morphine was administered. Due to the refractory muscular spasms intravenous phenobarbital started and little by little recovery was achieved. The patient receiving the first two doses of the Td vaccine, and discharged on Day 42 of hospitalization with no symptom recurrence. This case management showed adding phenobarbital to severe tetanus treatment regimen could significantly reduce refractory spasm caused by tetanus, also decrease other medication requirement.
