Ocular and Dermal Effects of Formalin on Medical Students (n= 140) Symptoms Number of the Students Affected Grade 0 Grade I Grade II Ocular Symptoms Excessive lacrimation
Symptoms include miosis, sweating, lacrimation
, gastrointestinal symptoms, respiratory difficulties, dyspnea, bradycardia, cyanosis, vomiting, diarrhea, as well as other symptoms.
Of these 28 patients, 13 (21%) had lacrimation
, sweating, or sialorrhea but 15 (25%) had body movement (extremities, facial muscles, and tongue) during laryngoscopy and intubation, coughing, or bucking, which necessitated the anesthetist's intervention.
Serous nasal discharge and lacrimation
was observed in the imidocarb treated experimental animals.
The acute effects of exposure can be caused by inhalation of formaldehyde vapors, which irritate the respiratory tract and eyes and cause lacrimation
, burning of the nose and throat, dyspnea, and headache and can result in pulmonary edema and pneumonitis (Kurose, Kodera, Aoyama, & Kawamata, 2004).
Although CR is less toxic, it has less systematic effect but more lacrimation
," said Abeer Mansour a medical toxicology scholar from Cardiff University.
Oedema, conjunctivitis and excess lacrimation
are common and termed 'Nairobi eyes'.
The pain is characteristically associated with ipsilateral lacrimation
, ptosis and rhinorrhoea.
Use of pupil size, lacrimation
, sweating and cardiovascular parameters alone are poor predictors of the depth of anaesthesia (Hadzidiakos et al 2006) and measurement of end tidal volatile anaesthetic agent concentration (ETAA) has become standard anaesthetic practice in the United Kingdom.
Exposure to these agents causes excessive salivation and lacrimation
in addition to seizure induction (Shih et al.
These include excessive salivation, lacrimation
, coughing and sweating.
2]S is an irritant to human tissues causing keratoconjunctivitis, lacrimation
, nasal irritation, dyspnea, and coughing.
