Peripheral trigeminal nerve block (TNB) with alcohol for trigeminal neuralgia (TN) is widely used as a percutaneous procedure for medically intractable TN. Mandibular nerve block (MNB) has been widely used in clinical practice as one of the most efficient blocks in V3 territory pain. Various local as well as systemic complications after the administration of alcohol injection, for example, dysesthesia, difficulty swallowing, ulceration of cheek, osteomyelitis, trismus, transient cranial nerve palsies, external rectus palsy, and diplopia, have been described in literature. We present the case of a spontaneous intracerebral hemorrhage in an elderly hypertensive patient after alcohol injection in pain clinic.
A 63-year-old (80 kg, 170 cm) male patient arrived at the pain clinic with a history of TN refractory to optimal medical therapy for the last 1 year. He had a history of hypertension and was on irregular treatment with basal blood pressure of 156/92 mmHg. He also had a past history of ischemic stroke with no neurological deficit and was on aspirin 150 mg once daily for the last 1 year. In the pain clinic, standard monitoring was done. Left MNB was given with 1 ml of 2% lignocaine with 0.5 ml of pure alcohol (dehydrated alcohol injection) under fluoroscopic guidance. Ten minutes after the block, the patient complained of slurring of speech with weakness in the right side of the body. On examination, his heart rate was 68/min, blood pressure was 216/116 mmHg, and oxygen saturation was 99%, with anisocoria. The patient was given intravenous (IV) labetalol 10 mg before shifting the patient to computed tomography (CT) scan. CT scan revealed left-sided basal ganglia and thalamic bleed (30 mL) with intraventricular extension and midline shift of 4 mm toward the right side [Figure 1]. Within few minutes of CT scan, the patient's Glasgow Coma Scale (GCS) dropped to E2V2M2 with irregular respiration, and emergency intubation was done. The patient's blood pressure was managed with labetalol 60 mg. To control raised intracranial pressure, 350 ml of 20% mannitol was infused. The patient was shifted again for CT scan due to sudden deterioration in GCS. CT scan revealed increased size of bleed with intraventricular extension. An emergency craniotomy under anesthesia was planned. He remained hemodynamically stable throughout the surgery. At the end of the surgery due to low GCS, the patient was not extubated and was shifted to the intensive care unit (ICU) for further management. The patient was kept in the ICU for few days before being shifted to the ward.

Spontaneous hemorrhage accounts for 20%–30% of all strokes and results in 30%–50% mortality over 30 days of presentation. A history of hypertension is found in nearly 80% of cases., Peripheral TNB with alcohol has long duration of pain-free period that depends on the nerve blocked. Mean pain-free duration in the recent study was substantially longer with alcohol injection in TN than those previously reported results. In a recent large study of 710 cases, 61 complications (8.6%) were reported with no mortality. The common complication was sensory discomfort which got resolved in few months. However, in patients with comorbidities, especially hypertension and on anticoagulant medications, TNB should be done with careful monitoring. Pain during procedure, especially after alcohol injection, may result in sudden malignant hypertension leading to various neurological complications. Dexmedetomidine and lignocaine IV can be used to blunt hypertensive response and intracranial pressure. Preprocedural assessment of patients, adequate analgesia, and peri-procedural monitoring will prevent these complications as well as lead to their early identification, if any. It is highly recommended to closely monitor hemodynamic changes in such subset of patients in pain clinic.
