Assessment of Dilute Epinephrine and Mechanical Pressure for Prevention of Feline Postoperative Scrotal Hematoma: A Randomized Controlled Trial

To determine whether two immediately postoperative preventive procedures, dilute epinephrine (1:400,000) as a scrotal wash or application of controlled mechanical pressure to the scrotum, reduce the risk or severity of scrotal hematoma following routine castration. Male cats with two descended testicles presenting to Midwestern University's Trap Neuter Return program were eligible for inclusion. Cats were assigned via block randomization to control, dilute epinephrine wash, or controlled mechanical pressure groups. For the epinephrine group, 0.2 ml (0.008 mg) of epinephrine diluted with sterile saline was instilled inside the scrotum. In the case of mechanical pressure, a broad-based clip generating less than 0.5 kg of pressure was applied for 10 minutes. Cats were evaluated for scrotal hematoma and the need for treatment by a veterinarian blinded to treatment group. Multivariable logistic regression was used to determine if the incidence of scrotal hematoma or scrotal hematoma requiring treatment was different between groups while controlling for other variables. There were 276 cats with a median age of 30 months (IQR 12,48) and a mean weight of 3.5 kg (SD 1.2). Scrotal hematomas were noted in 15 of the 92 (16%) control cats, as compared with 12 of the 92 (13%) epinephrine and nine of the 92 (10%) pressure cats. Treatment was required for 10 (67%) control, six (50%) epinephrine, and three (33%) pressure hematomas. Regression demonstrated a decreased risk of scrotal hematoma requiring treatment for cats in the pressure group (OR = 0.2, P = .044) controlling for weight (OR = 2.2, P = .006) and surgical duration (OR = 1.1, P = .026). Weight was the only significant variable for the presence of scrotal hematoma (OR = 2.2, P < .0001). Controlled mechanical pressure applied immediately after routine castration can help decrease the proportion of scrotal hematomas that require treatment.

Intracranial hemorrhagic infarct after local anesthesia on nasal mucosa: A case report

•

Epinephrine containing local anesthetics are used hemostasis in many cases.

•

We used lidocain with epinephrine for local anesthesia on nasal mucosa.

•

We present intracranial hemorrhagic infarction in a 41-year-old male patient.

•

Local anesthetic medicines with adrenaline can cause intracranial hemorrhagic infarction.

•

Checking correct dosage, and the use of basic vital signs monitoring are important.

Introduction

Epinephrine containing local anesthetics are used hemostasis in many cases. Otolaryngologists typically selected to decrease bleeding in surgery field for operations such as especially FESS (Functional Endoscopic Sinus Surgery), septoplasty, septorhinoplasty. In addition to known adverse effects of this local anesthetics agents they have rare complications too.

Presentation of case

We presented intracranial hemorrhagic infarction in a 41-year-old male patient after using lidocaine with epinephrine for local anesthesia on nasal mucosa.

Discussion

There are some publications like this case in the literature. In our case, a hemorrhagic infarction developed after giving the adrenaline/lidocaine infiltration to make up a local anesthesia in the mucosa of the septum. There is not any reported case like this in the literature.

Conclusion

We want to emphasize that all surgeons especially the ENT surgeons should be careful while using local anesthetic medicines which contains adrenaline for rare complication of intracranial hemorrhagic infarction. Another fact is that the patients must sign an informed consent form including those situations even for all minor surgical procedures to avoid a medicolegal problem.

Nerve block for the treatment of headaches and cranial neuralgias - a practical approach

BACKGROUND

Several studies have presented evidence that blocking peripheral nerves is effective for the treatment of some headaches and cranial neuralgias, resulting in reduction of the frequency, intensity, and duration of pain.

OBJECTIVES

In this article we describe the role of nerve block in the treatment of headaches and cranial neuralgias, and the experience of a tertiary headache center regarding this issue. We also report the anatomical landmarks, techniques, materials used, contraindications, and side effects of peripheral nerve block, as well as the mechanisms of action of lidocaine and dexamethasone.

CONCLUSIONS

The nerve block can be used in primary (migraine, cluster headache, and nummular headache) and secondary headaches (cervicogenic headache and headache attributed to craniotomy), as well in cranial neuralgias (trigeminal neuropathies, glossopharyngeal and occipital neuralgias). In some of them this procedure is necessary for both diagnosis and treatment, while in others it is an adjuvant treatment. The block of the greater occipital nerve with an anesthetic and corticosteroid compound has proved to be effective in the treatment of cluster headache. Regarding the treatment of other headaches and cranial neuralgias, controlled studies are still necessary to clarify the real role of peripheral nerve block.

Achieving hemostasis in dermatology - Part 1: Preoperative, intraoperative, and postoperative management

As dermatological procedures continue to become increasingly complex, improved methods and tools to achieve appropriate hemostasis become necessary. The methods for achieving adequate hemostasis are variable and depend greatly on the type of procedure performed and the unique characteristics of the individual patient. In Part 1 of this review, we discuss the preoperative, intraoperative, and postoperative management of patients undergoing dermatologic surgery. We address oral medications and supplements that affect hemostasis, hemostatic anesthesia, and intraoperative interventions such as suture ligation and heat-generating cautery devices. In Part 2 of this review, we will discuss topical hemostats. The authors conducted an extensive literature review using the following keywords: “hemostasis,” “dermatology,” “dermatological surgery,” “dermatologic sutures,” “electrosurgery,” “hemostatic anesthesia,” and “laser surgery.” Sources for this article were identified by searching the English literature in the Pubmed database for the time period from 1940 to March 2012. A thorough bibliography search was also conducted and key references were examined.
