Peripartum cardiomyopathy (PPCM) is a rare but serious form of cardiac failure affecting women in the last months of pregnancy or early puerperium. Clinical presentation of PPCM is similar to that of systolic heart failure from any cause, and it can sometimes be complicated by a high incidence of thromboembolism. Prior to the availability of echocardiography, diagnosis was based only on clinical findings. Recently, inclusion of echocardiography has made diagnosis of PPCM easier and more accurate. Its etiopathogenesis is still poorly understood, but recent evidence supports inflammation, viral infection and autoimmunity as the leading causative hypotheses. Prompt recognition with institution of intensive treatment by a multidisciplinary team is a prerequisite for improved outcome. Conventional treatment consists of diuretics, β blockers, vasodilators, and sometimes digoxin and anticoagulants, usually in combination. In resistant cases, newer therapeutic modalities such as immunomodulation, immunoglobulin and immunosuppression may be considered. Cardiac transplantation may be necessary in patients not responding to conventional and newer therapeutic strategies. The role of the anesthesiologist is important in perioperative and intensive care management. Prognosis is highly related to reversal of ventricular dysfunction. Compared to historically higher mortality rates, recent reports describe better outcome, probably because of advances in medical care. Based on current information, future pregnancy is usually not recommended in patients who fail to recover heart function. This article aims to provide a comprehensive updated review of PPCM covering etiopathogeneses, clinical presentation and diagnosis, as well as pharmacological, perioperative and intensive care management and prognosis, while stressing areas that require further research.

This prospective, double-blind, randomized, and placebo-controlled trial was performed to evaluate the effect of preincisional scalp infiltration with 0.25% bupivacaine on the postoperative pain perception and analgesic requirement of patients undergoing elective supratentorial craniotomy. Twenty patients (bupivacaine group) received scalp infiltration with 25 mL of 0.25% bupivacaine followed by intravenous 5 mL of saline as placebo 5 minutes before incision, and another 21 patients (fentanyl group) received scalp infiltration with a similar volume of 0.9% saline solution followed by 2 microg/kg of intravenous fentanyl 5 minutes before incision. Following standard anesthesia technique, basal, preincisional, and postincisional hemodynamic data were recorded. Postoperative pain was assessed at 1, 6, 12, 24, and 48 hours by using a 10-cm visual analog scale. Diclofenac sodium was used as rescue analgesic in the postoperative period. Results showed rescue analgesic was required only during the first 12 hours. In each group the same number of patients needed rescue analgesia, but bupivacaine delayed this requirement 105 (30-720; median [range]) minutes compared with 60 (15-720; median [range]) minutes for the fentanyl group (P = 0.13). But there was no difference in the amount of analgesic consumed at different time intervals. Six of 20 patients in the bupivacaine group required rescue analgesic at the end of 1 hour compared with 9 of 21 fentanyl patients (P = 0.61). At 6 hours, the fraction of patients who required rescue analgesia were 7 of 20 and 11 of 21, respectively (P = 0.44). In conclusion, bupivacaine preincision scalp infiltration did not have any significant effect on postcraniotomy pain and analgesic requirement. However, bupivacaine may delay the requirement of the first analgesic dose.

Over the last decade, the number of reported instances of lost guide wires during central venous catheterization has increased rapidly. Unsupervised or improperly supervised insertions of the central catheters by trainees, distractions during insertions, and high workload are the main risk factors. A retained guide wire increases the risk and cost of additional diagnostic and therapeutic interventions, as well as imposing many minor-to-serious life-threatening complications. Continuing education along with simulator-based skill development, vigilant supervision, and a shared workload during out of hours working are likely to prevent such occurrences.
