Nursing management of second trimester abortion by PGE2 suppository after cervical dilatation with laminaria or Lamicel focuses on monitoring and treating side effects, managing pain, and supporting the patient emotionally. Mean abortion time by this method is 15-17 hours, within 24 hours in 80% of women. The side effects expected from PGs are nausea, vomiting, abdominal cramps, and diarrhea. Premedication with transdermal scopolamine, and ancillary methods such as giving ice chips, airing the room, keeping the patient clean are helpful. Acetaminophen is given orally or rectally for fever, headache, or chills. A beta-adrenergic tocolytic drug such as ritodrine HC1 is given if uterine contractions become tetanic, contractions 2-3 per minute or lasting longer than 6-90 seconds, detected by palpation. This drug must be used with caution in patients with asthma. Pain management in midtrimester abortion depends solely on the woman's comfort. Meperidine, morphine, epidural anesthesia with bupivacaine, lidocaine or morphine SO4, or patient-controlled anesthesia may be used. The nurse should monitor side effects such as hypotension, allergic responses, arrhythmias, and inability to void. Midtrimester abortion is often a stress-filled experience, since women may be ambivalent upon learning of fetal abnormalities. The women should be monitored after delivery to ensure that her uterus remains contracted, and assisted if surgical removal of retained products is necessary. Patients teaching for discharge, including medication to prevent lactation, is described. A care plan is suggested for assisting the family with bereavement, based on that used in case of stillbirth or neonatal deaths.

Medical treatment of chronic cluster headaches (cluster headaches that occur frequently without remission) can be very difficult. In many patients, the pain remains severe despite all medication trials. For these patients, previous reports recommend radiofrequency trigeminal rhizotomy, which risks corneal anesthesia and subsequent corneal decompensation. As a safer, yet effective, treatment, retro-Gasserian injections of glycerol were given to eight patients having intractable chronic cluster headaches. Needle penetration into the trigeminal cistern, glycerol amount (0.55 ml), and length of patient elevation after the procedure (80-90 degrees upright for 10 h) were modified for maximal exposure of the V1 division. Three patients required one additional injection, and one patient required two additional injections. Verbal pain scales (means +/- 1 standard error of the mean) were: 9.1 +/- 0.30 (preoperative), 2.6 +/- 1.10 (1 mo postoperative), and 2.1 +/- 0.64 (1 yr postoperative). Daily headache frequency decreased from 6.0 +/- 2.0 (preoperative) to 0.2 +/- 0.09 (i.e., one headache every 5 days) (1 yr postoperative). Three of the eight patients had no headaches after 1 year. There were no instances of corneal or facial anesthesia. One year postoperatively, five patients required no medication, and three remained on low doses of medication for headache treatment. In contrast to previous limited reports of glycerol injections for cluster headaches, results with these patients having chronic cluster headaches support the use of glycerol injections as a viable treatment alternative, with significant pain relief and corneal safety.

Arteriovenous malformations (AVM) are congenital vascular lesions consisting of direct communications between associated arteries and veins without an interposed capillary bed. These vessels are typically thin walled, lack an internal elastic intima, and are quite prone to hemorrhage. A previously healthy 17-year-old woman presented with severe, persistent headache. After undergoing computed tomography (CT scan) and magnetic resonance imaging (MRI), the patient was diagnosed as having an intracranial arteriovenous malformation. The anesthetic management of this patient included induction with sodium thiopental and sufentanil. General anesthesia was maintained with isoflurane in oxygen and a continuous intravenous infusion of sufentanil. Neuromuscular blockade was established prior to endotracheal intubation with vecuronium and maintained with a combination of metocurine and pancuronium. The sufentanil infusion was discontinued when vascular isolation of the AVM had been accomplished. The isoflurane was discontinued 30 minutes prior to skin closure. Neuromuscular blockade was then antagonized with neostigmine and glycopyrrolate. Spontaneous ventilation resumed when the patient's arterial carbon dioxide tension (PaCO2) was allowed to normalize. The hemodynamic character of this anesthetic course was smooth and uneventful. The patient emerged from anesthesia comfortable and lucid and experienced no perioperative anesthetic complications.

The pathophysiologic effects of histamine in anaphylaxis have been shown to be mediated through H1 and H2 receptors, individually and in combination. H1 receptors mediate coronary artery vasoconstriction, wheezing, cutaneous vascular permeability, and possibly an increase in pulse rate. H2 receptors stimulate ventricular and atrial inotropy, arterial chronotropy, coronary vasodilation, and rises in basophil cyclic adenosine 3':5' monophosphate (cyclic AMP). (Neither receptor mediates increases in cyclic AMP in mast cells.) H1 and H2 receptors in combination seem to be most potent in mediating flush, headache, increases in pulse pressure, and decreases in diastolic blood pressure. Clinical trials have been conducted to determine the efficacy of H1 and H2 antagonists in preventing anaphylactic reactions to plasma expanders, anesthesia-inducing agents, morphine, and radiocontrast material. Concurrently, retrospective observations of the prevention of anaphylactic reactions to chymopapain have been recorded. Despite some conflicting and inconclusive data, the sum of these studies indicates that pretreatment with a combination of H1 and H2 antagonists is more effective than H1 antagonists alone in preventing reactions to these agents. These results, when added to the available knowledge of the physiology of histamine release, support the preferential use of H1/H2 antagonist combinations in the prevention and treatment of anaphylaxis and anaphylactoid reactions.

Malpractice claims filed against anesthesiologists for care involving obstetric (OB) anesthesia (n = 190) were taken from the American Society of Anesthesiologists' Closed Claims Database and compared to claims not involving OB cases (n = 1351). The most common complications in the OB claims were (percentage of all OB claims): maternal death (22%), newborn brain damage (20%), and headache (12%). In contrast, the most common complications in the nonobstetric (non-OB) group were (percentage of all non-OB claims): death (39%), nerve damage (16%), and brain damage (13%). The group of OB claims contained a proportionately greater number of minor injuries, such as headache, backache, pain during anesthesia, and emotional injury (32%) compared to the non-OB claims (4%). Complications due to aspiration and convulsions were more common among the OB cases. The standard of care was judged to have been met in 46% of OB and 39% of non-OB claims. This difference is not statistically significant. Claims involving general anesthesia were more frequently associated with severe injuries and resulted in higher payments than did claims involving regional anesthesia. Payments were made in a similar proportion of OB and non-OB claims (53 and 59%, respectively). For cases in which payments were made, the median payment for OB claims was significantly greater ($203,000) than for non-OB claims ($85,000; P less than or equal to 0.05).

This study examined the hypothesis that headache after general anesthesia is related to a caffeine withdrawal state. Two hundred eighty-seven patients undergoing minor elective procedures under general anesthesia were studied. Four to six hours after anesthesia each patient completed a questionnaire assessing his or her own alcohol, tobacco, and caffeine consumption, and the occurrence of postoperative side effects. A highly significant difference was found between the caffeine consumption of patients with and without preoperative (P = 0.0035) and postoperative (P less than 0.0001) headache. Logistic regression analysis of trend between headache and caffeine consumption suggested that with each 100-mg increase in caffeine consumption, there was a 12% increase in the odds of headache developing in the immediate preoperative period (P less than 0.0066) and a 16% increase in the odds of postoperative headache developing (P less than 0.0001). No relationship was found between headache and the patients' age, sex, usual frequency of headache, consumption of alcohol or nicotine, or the anesthetic agents or adjuvants used. It is concluded that postoperative headache is related to caffeine intake and that this relationship is explained, at least in part, by a perioperative caffeine withdrawal syndrome.

Propofol or methohexitone was given to the same twenty patients on two separate occasions during total intravenous anaesthesia for microlaryngeal surgery. With propofol the quality of induction was superior. Fewer patients required supplementation. Heart rate and blood pressure were well controlled at levels of 110-120% baseline. There were fewer side-effects during maintenance and recovery. Patients were able to return home earlier. However, apnoea and pain on injection occurred frequently, the latter when injection was made into the dorsum of the hand. With methohexitone, apnoea, abnormal movement, nausea, vomiting, headache, restlessness and confusion were common. Cardiovascular variables were poorly maintained at levels of 170-180% baseline. The results suggest that propofol is suitable as the sole anaesthetic agent in patients undergoing microlaryngeal surgery.

We report a case of meningitis caused by inadvertent introduction of bacteria following spinal anaesthesia for Caesarean section. The technique of performing the spinal anaesthesia is reviewed. Meningitis may occur, although very rarely, despite meticulous aseptic techniques. It is vital that meningitis should be considered in the differential diagnoses of post-spinal headache when patients present with headaches, pyrexia and meningism in the postoperative or postpartum period.

A 32-year-old primigravida showed signs of pre-eclampsia before delivery of a healthy boy at term. The CSF-space was accidentally punctured during epidural anaesthesia in labour. One day later hypertension was noted and the patient had a single generalized fit. For the next three weeks she had postural headaches, fluctuating hypertension, intermittent hearing loss and double-vision. On the 22nd day of postpartum, the patient had the first of a series of partial and later generalized seizures, followed by hemiparesis, alteration of consciousness, and finally slow recovery with corticosteroid therapy. Bilateral subdural effusions and generalized meningeal thickening were found on MR scans. Repeated MRI excluded sinus thrombosis and documented the response to treatment.

In this report we present aspects of the epidemiology of headache (i.e., pain in the head, face, ear, or neck) among children with brain tumors. The data are derived from the 3,291 subjects in the Childhood Brain Tumor Consortium databank. Overall, 62% of the children with brain tumors experienced chronic or frequent headaches prior to their first hospitalization: 58% of children with supratentorial tumors and 70% of children with infratentorial tumors. The relative frequency of headache increased through age 7 and then leveled off regardless of tumor location. For children under age 5, headache rarely had a duration of more than 1 year prior to hospitalization. Among children over age 4, headache duration of at least one year was significantly greater for supratentorial than for infratentorial tumors. Children with a brain tumor and headache had a different distribution of symptoms and neurologic signs than those without headache. Tumor location and headache status were interactively associated with the presence of other symptoms and neurologic signs. Children with headache had a greater number of other symptoms and neurologic signs. Regardless of tumor location among children with headache, nausea or vomiting, papilledema, and hypoactive tendon reflexes were more frequent, while upper extremity weakness, optic atrophy, and irritability were less frequent. Diplopia, coma, stiff neck, anesthesia or hypesthesia, pupillary abnormalities, and abnormalities of personality, academic performance, or speech were associated with headache in children with supratentorial tumors. No specific symptoms or neurologic signs were associated with headache in children with infratentorial tumors. Supratentorial craniopharyngioma, ependymoma, and protoplasmic astrocytoma were associated with significantly high rates of headache as was infratentorial pilocytic astrocytoma.
